You can see Wishes quite well from Narcoossee's. If you get lucky and get a window table--and get lucky again and have no one outside standing directly in front of you--you're in business.
IF you don't get a window table or if your view is blaocked, just go out on the deck. In fact, that's what we always do anyway.
If Wishes is at 9:00 and your ADR is at 8:50, Rusty Scupper is probably right--you may not even be seated when the fireworks begin.
