Stitch has gotten better since it's opening; it's basically Alien Encounter with a Stitch overlay. It's not fabulous, but as I said it has changed for the better since opening and is worth your time if it's not a long wait.
Philharmagic, on the other hand, is something you will want to experience again and again. It's breathtaking - amazing even. I'm not one for 3-D movies, but Philharmagic is brilliant. Sitting in the back gives you a nice feel for the 3-D, but the front is SO immersive when it's right in your face.
Cinderellabration...well, I guess Princess fans will enjoy it, but I much prefered the last Cindy show with all the villians and Mickey and such.
