I have always told everybody the best thing about disney is the way they prepare you for a ride. I have always paid attention to the preshows and walk throughs, with that being said, I will list some attractions that i love the preshow to. (please reply, I would love to hear what you think)
Tower of terror is absolutely tremendous, my favorite part being in the hotel lobby, they made that look sooooooo real! Everything about this preshow is great.
In RnRC Aerosmith is great, but the best part is when you go in the alle way, being from Boston I can tell you that it looks exactly like that.
Space mountain is also great because once you are inside that building it puts you in the mood right away. I love watching the TV's because it makes you feel lke you are in the future watching the "Space news"
Pirates of The Carribean is awesome. It has a very goonies feel to it which is great.
I could go On and On about so many other attractions like Big thunder Mountain, test track, alien ancounter, and splash mountain. But my alltime fav. is...................
Star Wars!!! Its so great, with the anomitronics outside and once you go in with C-3P0 and R2D2 working on the ship, its awesome, when i was little they had ewoks stand outside and great people, it was the best experience
