Mambo, generally I have really liked what you have posted on these boards, so I mean this with all sincerity .... just trying to give you some straight up experience.
Your booking of Wishes FP+ ... might not help you with personal space, it might, in fact, hurt you.
We had 3 bookings of FP for Wishes on our last trip over 14 nights, we also did 2 nights in the Hub, and 1 night in frontier land just outside the exit from BTMRR.
By Far, our Wish FPs were the worst. Why did we do 3 then? We had a semi split stay, first week was just my wife and I ... second week was a big group of people. So we tried it Once on our own and it was ok, another time on our own to see if it was going to be better and once with the group because they wanted to see what it was about.
In General - the angle, isn't very good. The Fireworks just don't give you the right impression from there, really. They are designed to be viewed from a direct view of the castle. You miss the impact of most of the castle effects to the left of the castle, and the big fireworks in general seem to be coming from behind the castle (which they do) instead of OVER the castle, the impression really is quite different.
Personal Space - Our 2 "solo" (two of us) times - First time, there weren't many people there, but CMs still INSISTED on making all of us cram forward toward the fencing, to make room for people that "might" show up. Well, they didn't frame it that way, but that was the end of the conversation I had with a CM. I explained to her that ... clearly there weren't many people here, no reason for us to cram in, we had just grabbed an ice cream and were sitting lounging and enjoying it ... but she insisted that we had to cram in with a subtle hint that if we didn't we might be ejected, because of people who "might" show up.
The Second time ... it was legitimately jacked. Its not a big piece of land they have reserved, and while we still go to sit, because everyone was sitting, there was no personal space. Peoples kids kept standing up in front of us, still had hands stepped on and people brushing up against us ... balloons in the way ...
Group time - The WORST ... it was jacked, and they had a section cordoned off for video recording equipment, we had an
ECV with us .... it was terrible. I wont chalk this up as a general experience due to the recording ... BUT, that crowd, even if they weren't set up, would have still had a really hard time making much room for anyone.
Overall - depending on the number of people booked for FP+ Wishes, it might be much more crowded than the Hub. There is a VERY finite amount of space, and they have to put all the people who have booked wishes FPs in that space, regardless of how the rest of the park is etc. So the Hub might be super crowded, OR, it might only be semi crowded with people generally having a decent amount of room, but the FP wishes viewing, if fully booked ... is going to be pretty crowded.
Our experience in the Hub .... I wont include the super rainy day because ... that was awesome ... there was no one there !!!
But in general, I think we had a much better experience viewing the fireworks from the Hub, and we didn't have to show up an hour in advance or anything.
Generally we hang back at the bottom of the roundabout of the Hub. Where mainstreet breaks into the circle. Here they clear the actual circle, BUT, if you stick to the mouth of the road, where it would widen into the circle, you end up with a fantastic view of the fireworks, and no one in front of you for 15 feet or so .... to us, this is the perfect location.
Just my experience in May .... maybe they have decreased the number of people they allow in for the wishes FP, so its less crowded (though I would doubt that, there weren't many people there to be honest) ... but even if that is the case, the angle just isn't right anyway ...
