Hi,
I'm not as experienced as other users to this site, but from my own experience...
When we have made ressies, I always request a general location (near pool, hospitality house, parking lot etc...). It seems that at busy times of the year, the earlier I check in (before 4PM) the better the chances of getting my location, even if I have to wait for the room, therefore we have to wait- not a problem, as we sit down for a bite to eat, and have bathing suits readily available for swimming. Good Luck!
