This is a nice tool, but you really can't go by it. While I might not get a room one day, there is no way to know that the room didn't open the next day. It's a nice guide to let me know I "might" have problems getting a particular resort on a particular night and reminds me that I better have a back up when I call, it's not perfectly accurate. For example: I post on it regularly and when I try to make a reservation and am told it's not available, I will ask, which days are not available. So while making a reservation recently I was told Jan. 16 and 23 were not open for BWV standard studio. But the other days were, so I only posted those days (16th and 23rd). Then afterwards someone may post that they tried for Jan. 16-23, so may have assumed the entire timeframe was not available, when actually I booked Jan. 17-22 and had no problem with a check out of the 23rd and I waitlisted for the 23rd. Make sense? I'm glad it's there and is a nice tool to gauge things, but still, you should always ask.
