We attended Party for the Senses this past year, and highly recommend it--the cost is somewhere around $100 per person as I recall, and it is a bargain--would not have felt cheated at double the cost. Last year was our first time, but we will book again this year.
We had one of the best evenings we've ever had at Disney, which is saying alot! Two things I would note, however:
1. Its not really for kids. There were a few kids there, but they were not enjoying it. It is really an adult function.
2. If you are a non-drinker you probably wouldn't enjoy it, as the wine flows freely!
The whole evening was themed as a sensory overload with food, wine, music, and the Cirqe de Solie performers. Awesome.
