I'm coming to New York that weekend also, it is considered a "blackout" time meaning there are very very few deals as most hotels are full and have waiting lists. It is all about supply and demand. A week later and prices go back to normal rates and there are bargains to be had. You can try bidding priceline. You could start with 4* MTW for $290, if rejected go to $300 and add MTE, and so on, gradually adding a zone and increasing your bids by $10. At the end, add in UES and UWS one at a time, as those are your free re-bid zones because there are not any 4* hotels in those areas, so it is like getting more bids in the same zones. If you want a nice 3.5* hotel, the only I know with halfway decent rates is the Affina 50 (affinia.com), and that is around $500. Sad, but true.
