All the interesting bits I remembered from previous trips years ago had gone when we visited in September. There was hardly anything to see apart from the few larger rides/shows which haven't been updated. Everyone was just walking around the shops and restaurants until queueing for the next show started.
Considering Universal is only up the road, I'm surprised that the MGM Studioes haven't been revamped to keep pace with the better film theme park.

The best "ride" at this park has to be "Tower of Terror". The walk up to the ride, and the inside of the "hotel" is scary in itself. It is by far the best attraction there. The Rockin' Rollercoaster is a great hit too. Other than that, I think this park needs an update. The Star Wars, Indiana Jones and all the other "older" hits are no longer interesting. C'mon Disney-change it up!!
Loved the Sci Fi restaurant and all the "actors" roaming around.

As for the heat---pick a cooler month people!! August is going to be H-O-T.

I thought MGM was just okay. If you are a big movie buff or love Hollywood, then I could see how it would be really enjoyable, but otherwise, I think it's just okay for Disney. The highlight of this park for me was the Lights, Camera, Motors Stunt Show. I'd recommend this for anyone, even those who are not into cars. It can get pretty hot, so I'd sit up high or by one of the fans, as the flames and pyros can make it even hotter up close to the stage. Also, this is a *loud* show, so be prepared if you have young kids that might be bothered by this. Star Tours is a good thrill there, without being quite as intense as other rides like Tower of Terror. The park seemed small compared to the others, and the theming not quite as nice as some of the other Disney parks. I'd say you could do this park in a half day, unless you are really into the whole movie/Hollywood scene, in which case, you'd probably really like this park.

I really didn't enjoy anything about this park. We went in Aug 07 and the heat was unbearable, the air-conditioning felt non-existent everywhere, I felt very sorry for the staff here.
My kids aged 11 and 15 yrs loved the aerosmith ride best out of everything. I didn't get to go on anything as either the rides broke down whilst we were queueing or the queues were too long.
I would never want to go here again.
