Below is a quickly done version of where I GUESSING the Parade FP+ area will be when they do move it to the Hub.
The yellow area shown is too close to the Castle to allow good, clear views of Wishes.
(That's an old photo of the Hub, so it does not include the new additions that have been made.)
** If MSEP FP+ was moved to the front of the castle again that would be wonderful. We were there last October and instead of moving to the FP+ area for Wishes we stayed put and I saw Celebrate the Magic for the first time! My new fav show at MK. **
We did feel it was a good spot for all 3 , even Wishes, although we did see a lot of smoke.
