Mousewait isn't working with the IOS 6 upgrade on iPhone 3G. I understand it works with the 5 but we haven't received ours yet.
I called the Ask Otto line at DLR (714-520-7090) to see what it's like. I called at 12:45 pm Disneytime. RSR 80 min wait no FP, Screamin 20 min FP return 1:20, No time available for POTC or Toy Story MM. Splash 40 min or FP 1:50. Star tours 25 min FP 1:30, Tower of Terror 15 min wait or 1:20 FP, Space Mtn 30 min or FP 2:55. Interesting!
