If you use the registration process at
www.aaic2013.com you will get what they refer to as the "conference Rate"it should be discounted. Two things but - you dont have to stay at the venue - there are a plethora of hotelsd and motels within short walking distance and secondly keep an eye on things like lastminute.com and wotif.com - their rates are sometimes cheaper than the hotels.
Hope tyo catch you there
