Waiting in lines is inevitable. You can plan down to the second, using 4 different touring plans, and you will, without a doubt, be waiting for something - a meal, a show to start, a bus to come - at many points.
What I like to do when I see people who are antsy in line (and lets face it, who isn't?) is help them to make it as fun as it can be. Play a game thats easy to play in line (see below), take out your digital camera and go through photos from previous days (make sure it was yesterday or before though. It's not as much fun to think "oh, that was fun, 10 minutes ago, when we met Goofy") etc. Before you know it, the line will be moving and you'll be good to go!
Games I like to suggest:
-Scattegories - pick a topic (Disney movies, presidents, Disney rides, foods, etc) and go through the alphabet thinking of one for each letter of the alphabet (i.e. Characters - Ariel, Belle, Cinderella, etc)
-Would You Rather Disney Version (Would You Rather....get stuck on Its a small World for 3 hours or have to spend 3 hours in the Swiss Family Treehouse?)
-I Spy (self explanatory and good for people watching)
