I've got two of them...
Adventure Express - nice family coaster, but not much theming, and the ending is really lame.
Yogi's SkyTours - great views of HB, but not all that exciting. There are pedals in the helicopters, but nothing happens if you pedal. The pre-recorded announcements during the ride are also rather lame. And yet, people wait 20 minutes or more to ride this (on really busy days, the line is 45 minutes or more).
