I think it depends on when you are traveling. When we were there we did the mama melrose fantasmic dinner package and was told to be at the back gate no later than 7:30p to get into the stadium. About 1/3 of the stadium was still wide open right at show time of 8pm. So we could've just walked right up and not have to sit there for 1/2 hr, plus the menu is different than you would order. It is so much $ per person, and it comes with a flat bread, entree, & dessert. (way to much food for us)
