St. Thomas vs. Florida Keys: Choosing a Winter Island Stay
When the temperatures drop at home, two warm-weather escapes tend to rise to the top of the list: St. Thomas in the U.S. Virgin Islands and the Florida Keys. Both offer clear water, slow island mornings, and winter days spent outside instead of bundled up.
They just deliver that escape in different ways. St. Thomas is a true Caribbean island, with ferries to neighboring islands and beaches you can walk to from your condo. The Keys are a chain of islands you can reach by car from mainland Florida, with reef trips, fishing, and boating close at hand.
At Swack Vacations, we host guests in both places: two condos on the east end of St. Thomas and two at Ocean Pointe Resort in Key Largo. This guide walks through the real differences, from getting there and winter weather to what your days look like and which rental fits your group, so you can choose the island that matches the trip you have in mind.
Getting There: A Drive Down to Key Largo or a Passport-Free Caribbean Flight
For many families, the trip itself is the first deciding factor.
The Florida Keys are the simpler choice if you’d rather drive. Key Largo sits at the top of the Keys, and our condos at Ocean Pointe Resort in Tavernier are a little over an hour from Miami. That makes it easy to fly into South Florida and drive down, or to make a road trip of the whole vacation. Plan on having a car once you arrive, since it’s the easiest way to reach restaurants, marinas, and parks along the Keys. Key West is about two hours farther south if you want a day trip.
St. Thomas is easier to reach than many travelers expect. The U.S. Virgin Islands are a U.S. territory, so U.S. citizens flying in from the mainland don’t need a passport. You’ll still need a valid ID for airport security, and it’s smart to carry proof of citizenship, such as a passport or a birth certificate with photo ID, for the trip home. The local currency is the U.S. dollar, so there’s nothing to exchange.
Two things to plan for in St. Thomas:
Driving is on the left side of the road, even though most cars are standard American models. Some guests enjoy renting a car to explore; others prefer taxis. Whether you need one depends on where you stay, which we cover below.
A side trip to the British Virgin Islands is international travel and requires a passport, so pack one if that’s on your wish list.
Winter Weather: Mild Keys Days vs. Warm Caribbean Sun
Both destinations are some of the warmest places Americans can reach in winter, but they feel a little different once you’re there.
Key Largo winters are mild and mostly dry. In January, average highs land in the mid-70s, with evenings dipping into the low to mid-60s. An occasional cool front can make for a breezy day, so a light layer is worth packing. It’s comfortable weather for walking, paddling, fishing, and long afternoons by the pool.
St. Thomas runs warmer. Winter highs typically sit around the low 80s, and the sea stays close to 79 degrees, which makes it easy to spend most of the day in the water. Winter is also the island’s busiest season, so booking early gives you the best choice of dates.
The quick take: if your group’s idea of a winter break is swimming and snorkeling every day, St. Thomas has the edge on warmth. If you want pleasant, mild days for exploring with less heat, the Keys are a great fit.
What Your Days Look Like on Each Island
The biggest difference between these two trips is how you’ll spend your time.
In St. Thomas, the days revolve around beaches and island hopping. On the east end, Sapphire Beach is known for calm, clear water and easy snorkeling right off the sand. Lindquist Beach, Coki Point, and Magens Bay are all worth a beach day of their own. From Red Hook, ferries run to St. John, which makes a day of hiking, swimming, and exploring a neighboring island simple to plan. Back on St. Thomas, you can browse the shops and restaurants of historic Charlotte Amalie, visit Coral World Ocean Park with the kids, or book a boat charter from one of the nearby marinas.
In Key Largo, the water is the main event too, but the pace is different. John Pennekamp Coral Reef State Park is about five minutes from Ocean Pointe Resort, making it easy to fit in a morning of snorkeling or diving. Fishing charters, dive trips, and boating are everywhere, and you can head inland for Everglades and mangrove eco-tours. Waterfront restaurants in Key Largo and Tavernier round out the evenings.
Ocean Pointe also makes slower days easy. The 60-acre resort has a pool, a 14-person hot tub, a private beach, a fishing pier, a snorkeling area, tennis and pickleball courts, walking trails, and a kids’ playground, so there’s plenty to do without getting in the car. Guests bringing a boat can arrange dockage at the resort marina through the dockmaster for an additional fee.
Where You’ll Stay: Comparing Swack Vacations Island Rentals
Our four island rentals are built for couples, families, and small groups, and each one suits a slightly different kind of trip.
Crystal Cove at Sapphire Beach puts you about a two-minute walk from Sapphire Beach. The king bedroom has its own ensuite, and an enclosed sunroom with a Murphy bed and privacy curtain gives a second sleeping space. Two full bathrooms keep mornings moving, and in-unit laundry makes packing light easy. Complimentary beach chairs, loungers, and towels are ready to go, and with a taxi stand next door, a rental car is optional.
Peaceful Paradise is the pick for groups of up to eight. The primary bedroom has a king bed and ensuite, the second bedroom has a queen, and the third has two queens and its own deck access, so families can spread out and still share the big balcony views of the Caribbean Sea. At Elysian Beach Resort on Cowpet Bay, you’ll have beach access, a pool with a swim-up bar, a hot tub, a fitness center, and tennis courts, and a resort shuttle runs until 9 PM. Red Hook’s restaurants and the St. John ferry are a short drive away. We recommend a rental car here, and since the resort is built into a hillside, some areas are reached by stairs.
Key Escape is a top-floor oceanfront condo with a private balcony facing the water, a renovated kitchen, and in-unit laundry. The king suite and a second bedroom with two single beds work well for a couple, a small family, or two friends traveling together.
Island Time has the same two-bedroom, two-bath setup with a private balcony and ocean views. It’s especially easy for families with babies and toddlers, with a crib, Pack ‘n Play, high chair, children’s dinnerware, and room-darkening shades available.
Both Key Largo condos share Ocean Pointe’s gated, 24-hour staffed entrance and include two parking spaces. The resort asks for guest names and ages before arrival, so keep those handy when you book.
A few things are true at all four rentals: each is non-smoking, none allows pets, and the minimum booking age is 25. Traveling with a larger crew? Mermaid Cove in Panama City Beach sleeps up to 12.
So, Which Island Is Right for Your Winter Getaway?
There’s no wrong answer here, only the island that fits the trip you’re picturing.
Choose St. Thomas if you want a true Caribbean feel, the warmest water, and the option to hop over to St. John for the day. Crystal Cove is ideal if walking to the beach matters most, and Peaceful Paradise gives a family or small group of up to eight room to spread out with full resort amenities.
Choose Key Largo if you’d like to drive or keep travel short from Miami, spend your mornings on the reef at John Pennekamp, and come back to a resort with plenty to do on-site. Key
Escape brings oceanfront views from the top floor, and Island Time makes traveling with little ones easier.
