In the past when there are no rooms on line and I call reservations (not the hotel directly) they have told me that they are fully committed for a conference and they are not releasing the rooms etc. This is usually for the big conferences.
Sometimes when the rooms are not available online I am still able to get them with dh ff miles but that is not the case all the time.
Even when I know it will be crowded like that, the conference attendees are always busy at the conferences.
But I know the Gartner conference is huge, so I dont think I want to deal with that. Think cloned guys, yes there were a few women there, walking around in blue shirts and carrying black laptop bags everywhere. No I am not making fun of anyone, its just what you have to deal with sometimes, like salmon swimming upstream if you want to go in a path/direction they are on when not at the conference.
Dh and I also had to deal with this when they had a thyroid cancer conference the other year. Oh and I didnt even know it was there and I have thy cancer too. Like a giant stream of dr.s being released from the conference area at once, yikes!.
Well, I hope it works out for you and you get the dates you want. That is why I always have a B Plan time frame if I cant get the dates I want.
