If by picnic fare, you mean buffet, then H&V is all buffet, every meal.
We have gone 2 years in a row for the Minnie's Holiday Dine and it was excellent!
The food was well prepared and fresh, and we loved meeting with Minnie, Mickey, Goofy (our host) and Daisy and Donald.
(DH and I are huge fans of Daisy and the Donald!)
There is only one price and you are allowed unlimited quantities of whatever you like...
We love it!
