I would definately park hop in the summer-maybe not in quiter times of the year. I had never seen Fantasmic and we had MGM schduled for day 3, but I just had this feeling about the weather. So on the evening of day 2, we park hopped over to MGM and saw Fantasmic on a beautiful night. the next night was overcast and off/on rain, and VERY humid. I am so glad we park hopped to MGM and saw the show on a perfect night. In the summer you are taking a chance that an evening show/parade might be cancelled because of weather. If you can;t park hop, you might be out in left field.
