I'm in favor of attending all the II's you can, at least until you have a few A's to make a more informed decision. The deposit you put down is already sunk. Unless money is super tight for you (or the flights are exorbitantly expensive right now), the travel expense won't mean much in the long term. Instead, you get the benefits of more interview practice, traveling to new places, meeting cool people, and maybe finding a program you didn't know you liked.
BTW Suwanee, GA is a nice, modern, suburban place. Rotations could put you in more rural places though.
