None of the three rides you mentioned are identical between DLR and WDW, but they are similar. The basic concept is the same in both parks, but there are small differences that a big fan of the attraction would notice (also the queues are generally different). Winnie the Pooh is the same basic story, but the scenes are in a different order. MK's version of Peter Pan is slightly longer (I can't remember why that is, but it's a little longer). Jungle Cruise is probably the most different...MK's version has an abandoned temple sequence that DL does not.
