I stayed at the property a few days ago. I booked a standard room and used one of my 4 confirmed diamond upgrades for a Atrium Suite.

At the time of the upgrade I requested 2 double beds from the diamond desk.

The suite was 1 standard hotel room with double beds, and the "suite section" was in the connected room. The connected room was the space of 2 standard rooms - had a big dinning table, a sofa bed, a few additional chairs, and a wet bar area. So overall it was the size of 3 standard rooms. Each of the 2 "rooms" had a full bathroom.

The room was numbered X71/X75.

Hope that answers your questions
