You mean the area by the computers? That part of the lounge is usually extremely quiet and I'd suggest that. Isn't that the Silver Bar or something? Because the main champagne area is right in the middle of the lounge.
Or, the terrace with earplugs+eyeshades. The terrace also has extremely comfortable plush sofa-like things that would be great for sleeping, as well as the chaise lounges facing the TV with the football.
