I'm going to bet the hall set up matches the one at C3, so I wouldn't count on being stuck between tables, but you're right Brent that it's something to have a contingency plan in place... What I'd do if I may suggest it, have some painted scenic backgrounds to hang behind the diorama, and have extras incase you've got 3 walls behind you instead of just 2.
For FFURG's booth, everyone had a corner... So you had 2 open spaces and 2 "walls" behind your area.
Just a thought you guys can consider for either format... I'd doubt you are between 2 other tables, but one never knows.
