I found the port-o-lets to be plentiful, and we especially appreciated the few running water & air conditioned facilities stationed around the show.
The port-o-lets were usually well maintained - until Sunday.
Please remember that those attending the Airventure on Sunday expect things to be run like every other day. It might just be this year (and the poor weather) but Sunday felt like everyone was just shutting down and cleaning up all day. Locking up the port-o-lets Sunday morning all over Camp Scholler was a let down (and those left open were in really poor shape).
