Best Family Resorts in Key West: Pools, Space, Beach, or Old Town?

Margaritaville works when the shuttle replaces a rental car

Margaritaville Beach House is across South Roosevelt Boulevard from public Smathers Beach. It is not an Old Town hotel and does not have a private beach outside the guest rooms. What it does publish is a useful family bundle: a lagoon-style pool, lawn games, family activities, daily parking, plus scheduled airport and downtown transportation. Some larger suites add a kitchenette and a separate living area.

That bundle earns its keep only when the timetable matches the trip. A family planning breakfast in Old Town, an afternoon nap, and dinner near Mallory Square may still need paid rides between shuttle runs. Read the current schedule beside the resort fee; the word shuttle alone is not the savings.

Parrot Key makes the most sense after bedtime

Picture 8:30 p.m.: one child is asleep, somebody still wants the television on, and the adults have nowhere to sit except the bathroom or balcony. That is the problem Parrot Key's suite and multi-bedroom villa inventory can solve. The hotel also lists four pools, lawn games, and scheduled transportation to Smathers Beach and downtown, but the door between sleeping and living space is the feature worth pricing first.

When Parrot Key quotes a suite or villa, open that unit's floor plan before comparing the price. Locate the bathroom, stairs, bedroom doors, and sofa bed, then check what the kitchen actually contains. The quiet, landscaped setting is an asset on days the family plans to remain there. It does not make an unscheduled Old Town dinner easier: that trip still has to fit the current shuttle timetable or include another ride.

Casa Marina earns its premium on resort days

Casa Marina's Atlantic frontage, private beach, two pools, and water activities can fill a day without a car trip. That is the stay that supports a beachfront-resort rate. If breakfast is followed by sightseeing and the family returns only to sleep, much of the premium is buying facilities they did not use.

Set expectations for the shoreline as well. This is Key West waterfront rather than a broad Gulf Coast beach with a reliably sandy entry, and weather, season, and sea grass affect what guests find. Recent conditions matter more than an old photograph. The booking record should also name the room category, renovation status, and every mandatory charge.

Count Old Town trips before giving up walkability

A family with Mallory Square at sunset, a seaport boat trip, two museums, and three Old Town dinners has already created several round trips. A genuinely central hotel turns many of them into walks. It also makes an early return after dinner ordinary instead of a transportation problem.

That advantage can disappear when a toddler needs a reliable midday nap, beach equipment travels everywhere, or the adults need two closed sleeping rooms. Compare a workable suite—or two rooms that legally hold the party—against the central option. The smallest Old Town room is not a bargain if the family cannot live in it.

• Best for suites and included transportation: Margaritaville Beach House.
• Best for multi-bedroom villa layouts: Parrot Key.
• Best for a traditional private-beach resort: Casa Marina.
• Best for an attraction-heavy itinerary: a genuinely walkable Old Town property.

Draw the room at 9 p.m.

Take a sheet of paper and place every person where they will actually sleep. Then mark the bathroom door and the only place an awake adult can sit. A listing that says “sleeps four” might be nothing more than two beds in one room; the occupancy badge cannot show whether flushing a toilet or opening the hallway door wakes the toddler.

Now circle anything the reservation has not guaranteed. Connecting rooms, a crib, a rollaway, and a particular floor are often requests. If the plan depends on a closed bedroom door, reserve a room type that includes one. Hope is not a room configuration.

Food needs the same literal treatment. A kitchenette may stop at a refrigerator and microwave. A family planning breakfast or bottle preparation should ask about the sink, stove, cookware, storage, and table before placing a grocery order.

For two rooms, draw the corridor too. Which adult is with which child? Where will the crib go? Would anyone have to enter a public hallway at night to reach a parent or the accessible bathroom? Two rooms can satisfy the hotel's occupancy rules and still produce an arrangement the family cannot safely use.

Trace the trip from the room to the water

Casa Marina puts its private waterfront on the property. Margaritaville guests cross South Roosevelt Boulevard to reach public Smathers Beach. From Parrot Key, Smathers requires the scheduled shuttle. Those routes are not interchangeable when the group is carrying a stroller, towels, and toys, or when a child needs a bathroom. Compare the route itself instead of treating all three listings as the same kind of beach access.

Conditions can also rewrite the day. Wind, heat, storms, and sea grass affect how appealing the water is, so a pool is a useful backup. For a non-swimmer, ask about the particular pool's depth, shallow entry, barriers, shade, hours, flotation rules, and lifeguard coverage. Four pools are not automatically four suitable pools.

Be equally specific about the hoped-for beach day. Digging in sand, swimming in calm water, launching a paddleboard, and sitting beside an ocean view are different requests. A hotel may deliver one and not the others without misdescribing its beach access.

A shuttle either fits Tuesday or it does not

Put one actual day beside the timetable. A 6:30 dinner and an 8 p.m. exit are incompatible with a return that has already stopped—or one that departs from the wrong end of town. The pickup point, stroller policy, reservation rule, and possibility of a full vehicle belong in that same check. Any gap becomes a paid ride.

Driving replaces the ride fare with parking cost and time spent finding a space. Rideshare removes the parking search but not the child-seat issue. Bicycles may suit older children and be useless for the rest of the party. Total the trips this itinerary creates; the transportation icon by itself has no dollar value.

Treat airport service separately. It matters twice, on arrival and departure, and only if its operating hours cover the flights. Ask where luggage waits outside check-in hours. If an airport-area room is in play, the room location also determines how much aircraft noise may reach it.

Save the checkout total, then finish the arithmetic

Begin with the final checkout screen for a room the family can actually use. Beside it, add uncovered food, local rides or parking, and required extras such as a crib or rollaway. Dates, sleeping layout, and cancellation terms must match across hotels. If the booking terms do not include an item, it is not a zero.

Breakfast is a common trap. “Included” might mean a buffet, continental service, or a restaurant credit for two adults. Check the hours against early tours. A room with a refrigerator and microwave may save more for a family of four than a small daily credit.

Put every mandatory resort fee in the lodging column. Then list what the family would otherwise buy. Parking and scheduled downtown rides can give Margaritaville's fee real value; beach or recreation services may matter at Casa Marina. An amenity that never enters the itinerary is worth zero to this comparison.

Now price the itinerary rather than the room. A central hotel can recover a higher checkout total by eliminating several rides. A suite farther out may supply parking and enough kitchen equipment for breakfast but add a fare after dinner. Run both stays through the same planned days; otherwise the cheaper room and the cheaper trip are easily confused.

Keep the cancellation exposure beside each total. The relevant date is when the money becomes hard to recover, taking account of deposits, cancellation cutoffs, early-departure charges, and named-storm terms. A prepaid discount is compensation for accepting more of the risk from school illness, airline disruption, or hurricane-season changes.

For a longer booking, read the room as living space. Laundry, refrigerator capacity, grocery delivery, and a table can matter every day. The final day deserves its own note if the flight leaves late: after checkout, will the hotel still provide luggage storage, pool access, changing space, parking, or airport transportation?

Replace the broad “family-friendly” label with the children's actual ages. A toddler can make blackout, balcony locks, pool barriers, a bath, a high chair, and the walking surface important. Teenagers expose different costs when Wi-Fi is poor, food is not within independent reach, or every outing requires an adult ride.

During storm season, medication, travel documents, and one change of clothes belong in carry-ons. Groceries and rented baby gear raise a separate arrival question: which entrance accepts deliveries and tour pickups? A sprawling resort may use several entrances; a historic property may have little room to hold an order.

The final reservation record should be short enough for every traveling adult to check. It needs the occupants, beds, mandatory charges, transportation arrangement, supervision plan, and cancellation terms. Anything the trip depends on but the record omits remains unresolved.

Check the entire route, not only the room

Start at the shuttle seat or unloading point and trace the path a stroller or mobility device must take to the room, restaurant, pool, and beach. An accessible guest room does not settle what happens along an outdoor path, ramp, sand crossing, or vehicle transfer.

For the pool, record the depth, barriers, shade, flotation rules, and whether lifeguards cover the hours the family expects to swim. Those details describe the facility; they do not establish child supervision. Treat an activities calendar as programming unless the resort identifies a staffed service that assumes responsibility for the child.
