Always, ALWAYS have your advanced dining reservations with you when you come to the park as you never know when you will need them.
If you do have early ADR's,having them available to speed up your trip in will be invaluable as you don't have to wait and do the "please get in that line and we'll look it up for you" dance with Cast Members.
Here are some easy storage tips for those #'s:
~ write them down on a slip of paper for your wallet (sorry, but it doesn't occur to some)
~Enter them in your cell phone.
~ Take a close up picture of the numbers and locations with your camera.
Also, here's a Camera tip:
Write down on a piece of paper, your local (at WDW) and home residences and contact phone numbers and take a Photo of it and keep it on your camera as Picture #1. If your camera gets "lost" the person who will find it undoubtedly will look at your photos and see the info for a chance to return it to you. Disney has TONS of Cameras that are turned in with lovely photos and NO IDENTIFYING info, how sad!!!
So I hope that helps!
Have a magical trip.....
