Easy airport. Controllers are very GA friendly. Elliot is only FBO on-field and they aren't overly friendly to us small bug smashers, but they get the job done.
Nothing unusual there that I can think of. I did my PP-ASEL training there 15 years ago (holy cow, has it been that long!?) in a lowly 152 and never had any problems getting in/out.
Depending on where your conference is, you might want to look at Davenport (KDVN). It's outside the C airspace, but close enough that you can get easy service for IFR in/out of there. Smaller airport that has a more GA-friendly FBO.
