The whole family did this four or five years ago and it was a blast. We were on the Grand Plan and so the tip was included in the package. You have a great view of MK and that part of the WDW from up high. On my turn some kids in watersprites went into the restricted zone and cause the boat to have to break and me to drop 25 yards. The lake patrol came out ran the watersprites off but it was interesting up there.
My two DDs did it in tandem and had a great time. The CMs gave them a signal fo cut the trip short (kicking their feet). The girls did not kick their feet at all but were flapping their arms like birds their entire turn.
Have fun.
