You dont say if you have ever been to
Disneyland before or how you are with thrill rides so I might adjust this depending on those answers. Here is my essential not to be missed list for an evening:
1.
Pirates of the Carribean*
2.
Indiana Jones*
3. Space Mountain*
4.
Haunted Mansion Holiday*
5. Peter Pan (see caveat below)
6.
BTRR*
7. Its a Small World* may be closed for holiday overlay
8. Jungle Cruise or Tiki Room
9.
Fireworks or Fantasmic! or both!
Asterisks are the bare minimum. I think that Peter Pan is the best of the classic Fantasyland dark rides (it is also one of my all-time favorite rides -so is on my must do list), but with your limited time, you may not want to spend it in line for this - the line is always long and the ride is very quick. If you don't mind the possibility of getting wet, I would add Splash Mt. I also love to prowl around New Orleans Square and listen to live music.
