I went last year and it was a great time. So different from WDW!
My favourite attractions were Crush’s Coaster, Space Mountain Mission 2 (my fave Disney ride ever!), and the theare show/movie with Martin Short…can’t remember the name of it.
4 nights is a long time to spend there though - we stayed 2 nights and found we had run out of things to do. Their studios park is a half day max, and Disneyland Park is a day (maybe 1.5 if busy). So since you have the extra time I would check out Buffalo Bill’s Wild West Dinner Show, lots of fun. Its in Disney Village.
Are you staying on property?
