They do dim the lights and pipe in the music. In addition, the waiters stop, and everyone stops eating and stares out the windows. In short, the restaurant and dining experience was haulted.
I made a PS for 55 minutes before the 9oclock show. We were seated 20 minutes late b/c I politely approached the podium and requested a window seat, which they didn't guarantee, but it worked out well. We watched Wishes and the water pageant, both of whch had music piped in.
It was great. And I bet the beach location will be great too!
