I'd keep the outer structure but demo the inside and rebuild as three full floors.

Top floor: indoor garden. Replace roof with glass. Family friendly.

Second floor: micro restaurants, micro watering holes. Make a bunch of restaurants/lounges that only have seating for 7-15 people. Rent each space out to a different chef, mixologist, or craft Brewer that doesn't have the experience or money to start their own full scale establishment. Create a labrynth of pathways for to get around so it's adventurous for patrons to get around. Each venue has its own vibe, decor, music, etc. Adult only.

First floor: a day and night club called the beach. Fake sunlight. Cabanas. Lounge chairs. Sand. Pool. DJ. Bottle service. Food service. Bars. Beach volley ball courts. Lazy river. Etc. Adult only.
