We just did this last week. Booked for a 5.45pm pick up to get a voucher for the 9pm show. We didn’t have any issue with the line being disorganised or taking a long time, maybe we were lucky. I had the ribs which I really enjoyed, we ate at the outdoor tables by the restaurant then went on a few more rides and came back at around 8.15pm, we were able to get a spot near the front which had a great view. We’d brought a picnic blanket and had plenty of room. If you need to pop out of the area you can do and they will give you a ticket to get back in, so the rest of the family got us a spot and got settled while I went out to the restroom and to get us all some churros. We stayed in the same spot afterwards and had a good view of the fireworks too.
