UUU1 looks like an exchange code. From what I remember the buildings are designated with A, B, C , D then a room number with the first number designating the floor. Building B floors 1 and 2 have the a view of the restaurant. Building A is on the seawall with the best Ocean views. Building C and D have views.
When you arrive you can speak with Gabby to see what's available for rooms. They will try to accommodate you. The Torres Maz is one of our favorites.
