It does sound fun! I go to a 4 day one, held twice a year, that is held up in Lincoln NH. They do offer classes that cost extra but everything else (room, food and soda, coffee etc) is included. There are around 140 people at each one. It's an awesome weekend but not sure if there are any airports near there either.
The smaller venue at Quail Hollow sounds like a lot of fun for getting together with friends.
