This question is like "How long's a piece of string?", but I'll ask it anyway. When does a hotel release pre-booked conference rooms to the general public? I'm trying to book NYC for 2 nights, 19th and 20th November 03. I got the 20th, no problem about 2 months back ($95 Marriott New York Marquis ) but couldn't book the 19th, I assume due to the Chemical conference at the Javits center 18-20th November. Their list of conference hotels is quite staggering and I assume they have block booked at the MM. The hotel web-site shows it is full for 18th and 19th but rooms are available for the 17th and 20th. So now I'm keeping my eyes peeled for sucessful bids around that time + bidding every week or so. However I'm concerned that this strategy may mean I miss the release date, so any clues as to when I should be looking would be appreciated. Ta
