20 Nights
William, I have a question on what constitutes a night. If I make a reservation for Saturday night but don't check in until 6am Sunday morning and I pay for the Saturday night (i.e. I flew a red eye and wanted to be able to check in early and was willing to pay for the night) does that count as a night? To me the obvious answer is yes since I paid for Saturday night even though I didn't check in until Sunday morning. However, I did this once with Marriott and since I didn't check in by midnight it did not count as a night. Thus, I had to pay but got no credit.
I actually have this coming up soon in two scenarios-early check in after a flight to South America where I am paying for the previous night as described above and check out late at night (i.e. 10pm) due to a late flight where I am paying for the extra night as well.
Thanks in advance.
By the way, I think the promotion is a good one as it has something for everyone. I will probably choose the 25,000 points for 20 nights.
