that was my question.
say i am on an assignment in city A, and book a room for a week.
on wed, i have to go to city B for the night, but don't want to check out of the roon in A (say there is a pay 3, get 4 promo running there).
Or even more interesting, for diamond requalification:
I check into 3 Hotels on Thurs. Check out of 1 on Friday, 1 on Sat, and the last on Sunday. Would I get 1 + 2 + 3 nights credited?
