If you're headed to Disney's California Adventure, someone with you might want you to go on Tower of Terror. It's their latest and my husband thinks their greatest. It scares me. You go up, all the way up, but you don't know you're going up because they distract you with a movie, then they open the doors so you can see how high you are, then they drop you down, then they keep doing it over and over.
My husband really likes it. He says the first time, he felt he needed to hold on. The second time, he didn't hold on and had much more fun. As for me, I didn't hold on the first time, then I did the next time! He gets one trip on the Tower each time we're there- I won't go more than once a visit!!
Have a great time!! Too bad Space Mountain won't be open until late July. That's the best one ever!!!
