Actually, if you are in the mood for that kind of food, Beaches and Cream isn't necessary such a bad deal on he dining plan.
For instance-
Beaches and Cream:
appetizer: Chili $5.99
entree: Double burger $9.89
dessert: No Way Jose $7.99
drink: Soda pop $2.29
With tax and tip = $32.56
Dinner at Boma's:
Buffet: $25.99
With tax and tip = $32.35
And in my view - two people could probably split B&C but there is no chance of anyone splitting a buffet.
