Yes there is. As the majority of people watching the show don't go to the dessert party, there are plenty of good viewing spots. I think it's unnecessary to do the dessert party strictly for the viewing. I also don't stake out a spot that early, 30 minutes usually does it.
FYI, they stopped the CL reserved viewing that originally came with the trial paid FP program back in Sept/Oct 2018. By many accounts, it was not particularly well utilized at any of the parks. The paid FP program still continues today, just not with the reserved viewing feature.
I was excited to see this until I saw the price and for the few things you get (glass of wine, keepsake menu), it's just not worth it. Nevermind, I'm not sure how anyone eats a full meal and desserts, then an hour later, eat at a dessert buffet. If they had priced it just for the meal and viewing area, I would've jumped. The addition of the dessert buffet isn't neccessary.
