I have 48 nights currently. If I don't get to Gold this year will 38 of those rollover to next year? If so I will get to Gold easily by the middle of next year. Is that better than getting there right at the end of this year?
If you are that close to gold status (two nights) they may bump you up anyway. You will have access to the lounge and a extra 5% bonus for each stay for the entire year which I feel is a good deal. My wife and I spent two weeks in London and Paris this past year and saved a bundle on food because we had access to the lounge. As a gold member many times you will receive a room upgrade.
