Thanks for the photos. If there are more floors, opening very unlikely in 2025.

Hyatt says it's the first Grand brand of Hyatt in Cayman. There was a (not-Grand) Hyatt late 1990's to at least Oct 2001, with Bamboo sushi restaurant (#1 or #2 sushi back then and not that many restaurants. Across the street was a canal, to catch the ferry to Stingray City and tip of the east side of the island. Along one side of the canal were hotel residencies and the other side (street name Palms Bay drive) with houses and small apartment complexes Lived/worked there a few years.

The film The Firm had some scenes shot at/near the former Hyatt hotel.
