We have done it three times. I would highly suggest getting a tier 3 table, on the balcony, off to the side. We did a tier 2 once and got the dreaded “table 99” which is our worst experience at Disney yet. (right in the flow of the wait staff, blocked by the wait staff so you can’t see anything). We did tier 3 this past fall and got a free upgrade, but I would have been really happy with a balcony tier 3 table again no problem.
The food is pretty good, the entertainment great, and the beer never-ending. Enough said.
We have never had any issue getting there. We usually just find a way to get to the WL if we aren’t staying there and then ride the boat over. Pretty quick and painless.
It is a great show, you will have fun!
