On the contrary, I highly enjoy the wishes FP
I was one of the ones who said I'd never use a FP for fireworks or parades, but after using Wishes once, it's a great FP to do.
We've done it twice now, first time on Easter weekend and second time last weekend. Both times were great. We were by no means crammed in like sardines like some people say they experience. Upon entering both times the CM's say "when the show starts it'll be standing room only". This is up to the guests within the area, the CM's don't force you to stand. Most of the people just choose to cram themselves together up near the front. If everyone really wanted to spread out and all sit, they could.
Now both times we've went to the back of the FP area and either sat on the railing, or sat on the ground and leaned against the railing. Few others around us, but most of the people were all standing up front crammed in next to each other. That was their choice. The projection show and fireworks looked just as good 20-25 feet back where we were, vs those standing near the front shoulder to shoulder. We sat and enjoyed it and had about 5 feet between us and the next few people.
Both nights were busy nights in MK, however I never saw anywhere close to thinking they gave out too many Wishes FP's and it was too crowded. If they really wanted to cram everybody in and take up the whole area, they probably could've put about 50 more people in on both nights we were there.
And the side that we prefer and have done both times is the FP area closest to Tomorrowland, the East side FP area.
