Best advice is you should have a copy made out of all the show times before you arrive at park
I thought it wasn't possible to get the show times prior to entering the park?
If you can get them where are they?
Try this website
http://pages.prodigy.net/stevesoares/index.htm
You can click on the parks across the opening page and it will take you to a list of all the different shows, locations and times. It is current for April but will update as you get closer. I think it updates on Sat or Sun for the next week. Usually once it gets in a certain season - it has very little changes from one week to the next. It even includes the smaller shows like the barbershop quartet that roams Main Street, different character appearances and a bunch of stuff I didn't even know existed.
If you just need fireworks, parades, Fantasmic, and Illuminations

While I am sharing that is a little OT - another neat website for characters is
http://home.att.net/~disneysue/characters/wdw/disneycharacters.html
You just click on the character and it will tell you the most likely place to find them !
