Best for families, anglers, and boaters who want a full-service marina plus multiple pools and casual dining across a larger resort campus.

Best for travelers who prioritize a polished beachfront resort with a full-service spa, multiple on-site restaurants, and a compact branded property.
When Three Waters wins: Choose Three Waters Resort and Marina if you want marina access (72 slips), a wider set of dining and casual options, multiple pools including a family-friendly swim-up bar, on-site kids’ activities, and connections to sister properties via a water taxi.
When Playa Largo wins: Pick Playa Largo Resort & Spa when you prefer a Key Largo beachfront location with an on-site full-service spa, fewer rooms and a more compact resort footprint, several on-property restaurants and bars, and the Autograph Collection brand experience.
Bottom line: Both are Marriott-affiliated waterfront resorts but play different roles—Three Waters is larger, activity- and marina-focused and better for families and boaters; Playa Largo is a sleeker beachfront spa resort for travelers who want a branded, beach-first stay.
