The best seats are probably in the middle sections so that you can see the best of eveything but to get these seats, dependent of the time of year you go, you would need to get there at least 11/2 to 2 hours prior. We left it till an hour before at the beginning of June and just managed to get a seat in one of the side wings.
However, wherever you sit you get a great view and we enjoyed the show immensely and you will too!!
