i like the seats on the side. but i would not do H&V, not a fan.
It does depend on when you go. during busy seasons, very helpful. Low crowd times, not so much.
If you have not done Fantasmic, it could be worthwhile to give it a try and see how it works for your family.
DO show up early though. They open up the reserved seating area before showtime and let the masses stampede in
