yes, supposedly, the reservations are sent to the resorts 5 days in advance, so within that 5 day slot is when they start to assign rooms...
personally i like one of two spots, depending on my mood..
if i want total seclusion, i ask for building 55 - it's really quiet, with a river view and far from any roads... and has a quiet pool as well...
alternatively, if i want to be near the main pool - and there's something to be said for that - then i ask for building 13, 12 or 11 (in that order)...
they're quiet (no road noise) and near the main pool....
but that's me...everyone has different preferences..
