Hi there, Alan!
Welcome to planDisney, it's great to meet you!
A dining package is the perfect way to enjoy Fantasmic! I'm sorry there's some confusion around your viewing area. Guests who purchase a dining package will be giving one voucher per person for access to a viewing area along the Rivers of America. It's the best view ever! These areas do require guests to sit on the ground. That way everyone has the chance for a good view of the epic show!
The voucher you are given will list the time of the show, as well as a return time for you to meet at a specified location to be given access to the viewing area. That being said, I would recommend arriving a little bit early if you're anxious to sit at the very front. You'll be able to leave and return if you need to, just as a Cast Member to give you a pass so you can get back to your viewing area. Sometimes we bring a light blanket to sit on to make it a little more comfortable. I also like to use the
Disneyland Mobile App to order a snack (hello, chocolate chip cookies at
Harbor Galley) that we can enjoy while we wait for the show!
If you're viewing the first show then you may also be able to stay for the evening fireworks if they're on the schedule! When we were there last week there were great projections on the Rivers of America as part of the show, and we enjoyed getting to see two shows from one spot. It was awesome!
Alan, I have to say that my all-time favorite nighttime spectacular is Fantasmic! Seeing Mickey's imagination come to life is just the best. I hope you love the show!
Keep moving forward!
Amanda
