I'm not saying it's the same view as watching from MSUSA, but it is a different experience. Most of the Wishes fireworks are shot from behind the castle, which is the same direction the windows look out and the windows are high enough where they can be seen from many areas in the restaurant. The lights are dimmed and the music is piped in. If it was the OPs only chance to watch Wishes, I would have suggested going with the earlier ADR, but since they have 2 days in MK, plus
MNSSHP, I personally like the idea of checking out the different perspectives. It's the same but different.
