Having just ridden the MK Peter Pan, I can say that there are differences. DL's doesn't have FP (already mentioned) and the boats actually stop to load/unload, unlike MK's where the boats travel on a continous belt in the station. DL's has steeper sections of track, which are not taken at a fast speed. MK's flys over much of the action, whereas, DL's flys by a lot of the scenes.
