Planning a first time visit to NYC. I've placed bids over the last couple of days without any luck. I am on a budget and am hoping not to spend more than $200 a night. Is it true that it is better to bid last minute for NYC? If so, how many days in advance would be considered last minute? Additionally, I am not opposed to breaking up hotel stays. Would it be easier to get good deals if I were to do bids for 2 nights rather than 4 nights?
