Quick Verdict: Casa Marina Key West vs H2O Suites

When Casa Marina Key West wins: choose Casa Marina if you want oceanfront rooms, a large private beach, multiple on-site restaurants and bars (Dorada, The Canary Room, Flagler's), a full-service Spa al Maré, multiple pools including a family pool and an adults-only pool, and extensive event/wedding facilities.

When H2O Suites wins: pick H2O Suites if you want an adults-only, small-suite property with private plunge-pool suite options, very high guest ratings, and a location a short walk from Duval Street, South Beach and Key West’s Old Town attractions.

Bottom line: Casa Marina is a full-service, historic oceanfront resort that better fits families, larger groups, and guests prioritizing beach and resort amenities.
