Best for travelers who want Key West’s largest private beach, larger event space, and family-friendly pool options.

Best for travelers who want to be steps from Duval Street, Mallory Square, and harborfront dining and sunsets.
When Casa Marina Key West wins: choose Casa Marina if your priority is beachfront access, on-site watersports launching from the sand, larger resort grounds with two oceanfront pools (including a dedicated adults-only pool), and wide event/wedding options.
When Ocean Key Resort wins: pick Ocean Key if you want to be in Old Town at Mallory Square/Duval Street, favor harbor and sunset views, prefer a smaller, more intimate waterfront property close to nightlife and galleries, and want direct access to waterfront bars and piers.
Bottom line: Casa Marina is the better fit for beach-focused stays, families, and larger events; Ocean Key is preferable for a compact, central Key West experience with immediate access to Duval Street and Mallory Square.
