We are not very interested in many of the rides at HS either. Not a star wars fan. Half a day is perfect there!
We fill our day with shopping, shows and a restaurant. They have some pretty cool and unique restaurants, my favorites of all the park.
The Sci Fi Diner is so cool and since the menu change, the food is actually good. If you like fried chicken and comfort food with a little humor, Primetime is your place. Woodys roundup is perfect for BBQ lovers, all you care to enjoy, so much food, the salad and cornbread are really good and its a fun atmosphere, its my wife's favorite.
Tons of stores for merchandise lining their "main street" all the way up to tower of terror. Some of my favorite ornaments and souveniers are from there. The new little mermaid show is fantastic and they have the new villains show.
