If it's a mad house leaving MK after Wishes, which it was on my last visit...instead of waiting in line to get back to your resort...I suggest making a stop at the Milestones of Animation Theatre in Main Street (on your left hand side as your leaving the park)
There is a small theatre in the back that shows cartoons non-stop all day. There is plenty of room to stretch out, it's usually quiet, and they don't shoo you out.
We sat in there for 45 mintues last August, and it was still a Nutt House when we came out. Next time, we'll stay even longer!
