There's an app I got on my Droid Incredible - I feel safe in assuming it's available for iphones, too - called "Ride Hopper." I only have the free "Ride Hopper Lite" version, but they have various parks throughout the country, including the Disney Parks, with wait times and notification if a ride is closed. Consider getting it as a compliment to the links below, as they are beneficial for planning before you go. But rides may need to be shut down for any number of reasons without advance notice, and having up-to-date info on your phone (provided you have a phone that can get the app) could save you a bit of time and a bit of heartache. Welcome to the boards & have an incredible trip.
