By the way, when you say "loud", just what is it that you mean?
You might want to check out the Mayan Princess too. It has a couple of rooms that might suit. There's a room on the second floor on the southside that is a suite and has a large separate bedroom, with two fullsized beds in it, IIRC.
Room #15, is an ordinary suite, queen bed in sleeping area, queen pullout in seating area, but there is also a small (really small) bedroom with bunkbeds in it. This small room, is connected by a little hallway, that is shut off from the main hotel hallway by the hotel room door. But on top of that, the small room has it's own door and so does the main suite.
Last year, I had that unit and some friends came to stay with me. Worked out great! Only little hiccup in the arrangement (for me) is that the bathroom is right beside the sleeping area. Well, OK, it was only a hiccup for me when my friends staying in the little room, wanted to use the facilities when I was trying to sleep.
