We will wing it then. Honestly I care more about viewing position for Holiday Wishes and Peace on Earth.The real issue is last year, when both were being shown, it as SWAGS first, then F! and JBJB last. Star Wars was packed when I was there, which was between Christmas and New Year. However because there was no Desert Party for it, we simply walked up from Echo Lake and got a spot in front of one of the pillars. Brilliant view, and that was about 30 minutes before. A CM did tell us we would have to move before JBJB because it was a reserved area, but that was OK.
So no real direct comparison is possible. Also bear in mind the day we went was a few days after Carrie Fisher passed away, so the atmosphere was quite unique. I have never heard a crowd "roar" by way of appreciation quite like that evening. Pretty poignant.
