Can't complete my schedule until i know if they are every night, 2 xs per week or what. Also, what time is the show usually? Have little ones, so have to have a good plan of action! We are going the first week in december.
They both run every night. Fantasmic can be cancelled due to bad weather. Last year Fantasmic started at 7pm the first week of December and Illuminations at 9:30.
When I was there in June, Illuminations was every night but Fantasmic was not open on Wednesday nights. We actually park hopped on Sunday from AK to MGM so we wouldn't waste so much time the day we had dedicated for MGM waiting in line for the show. It worked out very well. Enjoy!
