tjkraz's post got me thinking (yep, twice in one week - can my brain stand all these thoughts?):
I agree that Friday is the biggest check-out day, and Sunday is the biggest check-in day, but wouldn't Saturday be the best day to check-in, at least with regard to both getting.a.room.early and getting.your.requests? Yes, a lot of people check out Friday, but doesn't that overload Housekeeping, if they have to do a full cleaning on 30 or 40% of the rooms? At least I think that there wouldn't be a lot of rooms available until later in the day.
But Saturday, a lot of the rooms that DVCers will check into will have been empty Friday night, so they can get them early.
Hmmmmm.............
