We much preferred AK, but I couldn't get anyone to go on the coaster or Tower of Terror with me. If they like thrill rides, MGM is probably better. The one thing to consider at MGM is that the shows are only at certain times. If you only have a morning, you won't get to see more than one or two. We had a lot of down time, waiting for a show to start. At AK, there was too much to do, and it was all such fun! Have a fun trip!
