I don't recommend anything in the "other" building - it's just too far from the coffee machine in the lounge =p. Last trip they put us in a large room (not quite what I'd call a suite, but much larger than the rooms I get in the tower) and we only barely made it to the room before deciding we didn't want to make that walk over and over. They happily put us in a tower room (just below the club floors that were being renovated) and even checked the next day to make sure we were alright with the bed change we'd accepted to get into the tower.
Anyway, I figured I'd post to say that I would NOT burn SNAs for anything in the loft section unless I desperately needed the extra space. I'd also call the property directly to see if they could perhaps manually approve the SNAs for a room you like. I've never had a tower suite there, so I can't speak to their location, but the tower isn't huge so nothing there would be inconveniently located.
