There are always pros and cons to any special event. We're doing it this year simply because we never have before

and I always add 1-2 new things each year. I'm interested in the view of the fireworks from this position, and the ability to relax while the park clears out and then take our time to exit. There's several threads on both WISHES dessert party and Tomorrowland Terrace dessert party (since the fireworks are no longer called Wishes), so search the board if advice is your decision-maker.
