Right now, the existing Seminole Hard Rock Hollywood hotel has almost 500 rooms, as well as a casino, meeting space, restaurants, and a lagoon pool. At the tower’s base, guests can swim underneath waterfalls in plunge pools, relax in private cabanas, and partake in water sports in a giant artificial lake. The 450-foot-tall hotel will boast more than 600 rooms, around half of the complex’s total, plus a 41,000-square-foot spa and a few restaurants.
