It depends on your group and interests, but here is my list:
POTC
HM
Matterhorn
Peter Pan
Alice In Wonderland
Storybookland Canal Boats
Turtle Talk With Crush (at DCA)
Wait time depends on time of day, day of the week, and time of year. In the first couple hours of the day, and last couple hours, all rides are pretty short - 0-15 minutes.
POTC and HM seem to max out at 35-40 minutes mid-day.
Matterhorn maxes out at 45 minutes.
Peter Pan maxes out at 60 minutes.
Alice maxes out at 40 minutes.
Storybookland maxes out at 40-50 minutes.
TTwC is usually one show cycle, about 20 minutes max.
