I know the place well, it is one of a few spots they use for VIP viewing. Fine to use but you do risk being moved on, which can be a little embarrassing.
The show is an ariel show and and all positions are good, except downwind which can be a bit foggy.
We used to avidly grab a front position and stand waiting got sometime. Thenwe realised it was more fun to stand back behind the crowd in any of the raised areas. Lots more room, great view and easy access to concessons. During busy times you will beat the crowd out of the park too.
