I managed to get a full pass because of a tip to use the facebook link, but then came back ten minutes later and tried to register a guest who was having trouble logging on as an AHA member and the waiting list was already up. Seems like this took less than an hour to sell out. I managed to get the Wed, Thurs, Fri hotel, but they were sold out for Sat. night.
It just doesn't seem like a huge improvement from last year even though I know a lot of effort was made to make it work more smoothly. If it had not been slow at work this afternoon, I'd have been shut out.
