It isn't the number of nights. It is the number of stays. I realize I am only silver but that meant a lot to me.
I stayed more nights than needed but it is the stays that count. So I am staying at a Marriott this weekend to keep Silver.
Next year will be a busy year and I will earn it easily. When I sent an email to Marriott Rewards they said there was nothing they could do for me. I didn't like the answer but will do another stay to keep my Silver.
