I would suggest one of the seven “main” properties where the event is taking place as the first set of choices. If you can’t get in to one of those hotels, one of the seven “sleeping” properties to get good, discounted price.

Unfortuantely, we don’t have enough information to make an informed choice at this point. My guy says Aria or Venetian/Palazzo since they are hosting the Quad and Expo respectively.
