There are literally hundreds, perhaps thousands, of hotels in New York City. I visited about 100 of them and judged on convenience, price, comfort, location, and again PRICE. When we booked our wedding date, we didn't realize it coincided with the busiest hotel season.
The majority of the rooms blocked are at Roosevelt Hotel on 45th at Madison, near Grand Central Terminal (connects to JFK and LGA). The hotel is majestic and this is where our next day brunch will be. We've also blocked rooms at the Grand Hyatt which is two blocks away. Not too far from there, we have a room block at Mariott Courtyard Inn. These are all midtown and about a 10 minute cab ride away from the wedding site.
If you're interested in staying in a more "hip" hotel downtown, then we have rooms blocked at Hotel On Rivington, which is in the heart of the Lower East Side, near the wedding site. Soho Grand Hotel and Tribeca Grand are also very close by and offer great accommodations.
See below for a full list of room blocks and also some recommendations where else to stay. Of course, all are welcome to stay at any hotel of their choice.
