How Sirene fits inside the larger resort
JW Marriott Marco Island Beach Resort is a large, family-friendly Gulf-front property with multiple pools, a waterslide and on-site dining. Sirene is a dedicated adult enclave within that larger footprint; Sirene guests can use resort restaurants and services while retaining access to Sirene-only areas.
Expect a convention-scale resort environment outside Sirene: the property lists dozens of room types, 12 on-site restaurants and extensive meeting and event space. Sirene provides a quieter staging point within that busy resort.
- Overall resort features to be aware of: three outdoor pools (some sources list four), a family Tiki Pool with waterslide, Spa by JW, fitness center, and 12 restaurants and bars.
- Sirene guests share on-property dining (for example Tesoro, Ario, Quinn's on the Beach) but have separate Sirene spaces reserved for adults.
- The resort sits on private Gulf-front beach frontage and is at 400 S Collier Blvd, Marco Island, FL 34145.
