I got an email with my MR summary today and it had special for the Budapest Marriott: third night free 11/01/07-01/31/08. It also says 99-135 euros/night so I thought that 3 nights for ~250 euros... I may see if it's worth making my way there. I click to see the hotel details, and low and behold:

The hotel is refurbishing the lobby, executive lounge, and health club beginning September 26, 2007 through February 1, 2008.

No lounge, no health club + construction... no thanks.
