We did it a few years ago and it is nice to have a seat waiting for you instead of fighting the crowds. The desserts, coffee and drinks are a nice bonus! Don't expect anything over the top in the way of desserts but they are good. As a PP said, the angle isn't "perfect" but then there are on a few places on Main Street that are. To me it was worth the $$ though I probably wouldn't do it again. Enjoy!
OOPS I just read the OP again and I assume too that you are talking about the Dessert Party??
