OK.
Every choice has pros and cons. Yes the seats are off to the side but you do not miss anything. Most of the show is set back and easy to see. You will walk away amazed if you are anywhere in the theater.
If you have a night that you really want to see the show the Fatasmic package is a great idea. You are guaranteed seating, you will have a good meal, and you won't have to wait 90 plus minutes. If the show is cancelled you will have no show and a good meal.
We like it because it is a nice relaxing dinner and unless the show is called off we will see a great show! I just don't have enough patience to wait over an hour and a half - the park time is too important.
Good luck with your choice.
