They do go rather quickly so now would be good...I made mine a couple of weeks ago. There will be many people there for the Beinfeld show and I mean Many!
I got my room a few weeks ago There really is nothing to gain by waiting to book your room however be aware that they do bill you for one nights stay at the time of booking that can be an issue for some people Naturally if for some reason you have to cancell it would be refunded
