Enchanted Tiki Room : The Tiki room is the same as it always has been. The new version at WDW is fun but. It starts out the same for a minute and then veers wildly in another direction.
Jungle Cruise: These are essentially the same except
Disneyland does not go inside any temple.
Haunted Mansion: The buildings are very different on the outside. The Disneyland version has stretch rooms at the beginning that actually are elevators and take you down. You walk through the hallway of portaits that you ride through at WDW and WDW's has a couple other scenes at the beginning that Disneyland does not.
Pirates of the Caribbean: It is almost twice as long at Disneyland though they both have almost all the same scenes the one at Disneyland has areas of bayou and caves and longer drops that stretch the ride time out. The last scene at WDW is different.
"Honey, I Shrunk the Audience" This is the same with a slight improvement on the in theater effects.
"it's a small world": The loading areas are very different. At WDW the boats travel through a trough that you can see down below (not as nice looking) but there are a couple more rooms you go through. The last scene at WDW is much better.
Peter Pan's Flight: This ride is shorter at Disneyland but prettier in spots. Each boat operates on its own instead of them all moving and never stopping like at WDW. There is a fun swooping motion that occurs on the Disneyland ride.
Snow White's Scary Adventure: These have a similar feel but many of the same scenes and many different scenes. The DL version ends rather abruptly.
I would make sure you do the very different rides at Disneyland like the Matterhorn, Indianna Jones, Alice in Wonderland and the Storybook land Boats and then try to fit in the things that are similar...except for Pirates and the Haunted Mansion which are always great. It really is fun though to compared the attractions between the two parks.
Hope this helps.
