We did this earlier this month. I was concerned about not being able to see the Big Screen, but we booked anyway. We watched the show on 10/2 at La Hacienda which was not good and we went outside halfway through the show.
We loved this! you are directly between 2 of the side barges, which is great. Would it be a better view from the front, absolutely, but I think the boat is MUCH better than the other 2 dining packages. It was also an amazing experience.
I will be posting a video tomorrow (12/22) on YouTube.
