Hmmmmm, well, this might be nice for folks who like to dance. I think $65 is a little steep for miniature desserts and a fireworks viewing place (since there really are no great viewing places from that entire area- just the high explosions can be seen).
I would not pay that much, either.
Just giving those that have that kind of cash to burn the option.
I remember when you (for the price of $79) could party all night on PI with a full buffet and all drinks included. Yep. That was some time ago. (Very late 90's).
