It is in an outdoor covered pavillon. The tables are picnic tables and there is a dance floor and stage area. The food is at the back of pavillon as are the drink stations.
The characters do not go around and visit each table. They do however come out to dance and you are welcome to join them. So no autograph opportunity, but plenty of pictures.
As for worth 2 TS credit I think it depends. You are getting buffet food, but at the same time it does include beer & wine for adults. Entertainment is great and you know you are getting 3 hours worth if you stay the entire time. Not sure I would want to spend 2 TS credits on this over say a meal at Cali Grill. But for families where Cali Grill would be out of question because of the kiddos then I think it would be worth it.
We are going back on Oct 6th and are really looking forward to it
