The St. Regis Longboat Key Resort

The honest review

The St. Regis Longboat Key opened in 2023 and almost immediately reset the bar for luxury family travel on Florida's Gulf Coast. The headline attraction is the 500,000-gallon saltwater lagoon, a sprawling ecosystem stocked with nearly 40 species of fish and actual stingrays you can interact with through supervised encounters. Adjacent to the lagoon, the resort keeps two resident tortoises — slow-moving celebrities who generate an outsized amount of delight among kids who have never seen one up close. This is not manufactured resort theater; it is genuinely memorable.

The Reef Rangers Kids' Club (ages 5–12) provides supervised programming that spans beach ball decorating, lagoon snorkeling introductions, scavenger hunts, and video game tournaments — enough variety that children with wildly different interests will both find something. The club operates on a fee-per-session basis rather than being bundled into the room rate, which is worth factoring into budget planning. Three heated pools, including one with a lazy river, give families a solid aquatic menu even on days when Gulf chop makes ocean swimming less appealing.

Rooms start at around 470 square feet in the Superior category with partial water views, and scale up through Deluxe and Grand Deluxe Oceanview configurations (~545 sq ft) to multi-bedroom suites that can genuinely house a family of five or six without feeling cramped. All rooms feature private terraces. The resort also stocks a thoughtfully curated treasure chest for arriving families — stuffed animals, activity books, kites, card games, juice boxes — a small touch that lands well with younger children after a long travel day.

For parents, the full-service spa and St. Regis Butler Service mean recovery time is actually recoverable. Multiple dining options range from casual poolside fare to more refined evening service, and the kitchen can accommodate most common children's dietary needs without a fight.

The honest caveat here is price. This is among the most expensive properties in Florida, period. Rack rates in peak season (January through April) routinely exceed $2,000 per night, and the resort fee plus mandatory valet add meaningful cost on top. Families who stay here in shoulder season (September through November) can find rates closer to $900, which still represents a significant investment but makes the math more defensible. For families celebrating a milestone event — a grandparent's retirement, a special birthday, a reunion — the St. Regis Longboat Key delivers an experience that justifies its price. For a standard summer week, most families will find better value at one of the island's other solid properties.
