Our first recommendation, The Muse was going for just over the limit at $459 a night. BUT the hotel is offering a special 15 percent off rate if you book six nights or more, making it a doable $390 a night. Again, before taxes which are a lot in NYC.
Same thing was going on at Hyatt 48Lex which had rooms starting at $459 a night but booking an advance purchase rate got the rate down to about $413 a night. A better deal can be found at the Muse's sister hotel, 70 Park Ave for $254 a night for a King Deluxe room which we found on Expedia.
We also noticed that the fancy schmancy New York Palace hotel was also available for $413 a night on Expedia. That's for a superior guest room (aka no view) with a king bed along with a couple of Expedia extras including free dessert at participating BR guest restaurants. Interestingly, there was no such "deal" to be found on the hotel's website. They were quoting a total bill of $4,273.64 while Expedia was "just" $3,344.17. See, kids? Always, always shop around.
