The first time we went to Fantasmic, we went without the package. We sat at the far left side when looking at the "stage". Boy was that a pain when the show ended. I think it took close to 1 1/2 hours to get back to the resort with much of it trying to get out of the Fantasmic area and out of the park!
The second time we did the package and sat in the reserved section on the far right. I know the view is somewhat better in the middle section, but it was worth being on the right side when the show was over. We were home in less than a 1/2 hour! That alone was worth the money with two very tired children.
