Arabian Nights is very close to WDW. The entrance is on Route 192 just east of I-4.
It's an extravaganza featuring beautifully trained horses dpoing everything from intricate dressage to cowboys and Indians routines. It's performed in a huge arena while you eat dinner. The show is definitely the star here; the food won't win any awards.
If you like horses, you'll probably love the show. It's regularly voted favorite dinner show by Orlando locals.
