We watched Wishes from the observation deck just last month (the one further away from MK) As previously posted it is an awesome view. Then as wishes was ending (10 p.m. that night) we were able to also catch the Electrical Water Pageant as well. This was our 3rd visit to CG and our first time seating on the far left of the restaurant (as you are facing GF). Both other times we were seated on the right. I didn't realize that the area on the left was so big. We were seated at a window but it was a side window and I had my back to it. So, we didn't really have a view at all and needed to watch from the observation deck. Previously we had a window seat with a great view of MK, etc. but we would have been better to do on the deck as the lights weren't dimmed in the restaurant and everyone left inside was so loud that you couldn't hear the music that was piped in very quietly. I tried to film part of Wishes that time (9-06) but mostly what I captured was the reflection of the room in the windows and the background noise. First time (9-05) the windows were completely covered with condensation so we had to watch outside anyway.
HTH.
