DW and I have been to Cape May dinner buffet twice. I agree with the writer who said you should stay away if you love real good seafood. While it is a pretty good buffet in general, the seafood leaves a lot to be desired. As a shrimp and clam lover, I was very disappointed with a meal that is billed as a New England Clam Bake.
That being said, I have to give them high marks for their dessert table. It is one of the best at WDW.
One caution - Of course you need ressies to get in, but you stand a better chance of being seated if you are a large party since they have more large tables. DW and I went ourselves and waited one hour after our ressies because they did not have a table for 2 available. We stood by and watched parties of 8 and 10 being seated. It was very frustrating.
If you want to experience Cape May, go for the breakfast buffet. Our party of 12 (the whole family this time) was quickly seated and had a wonderful character breakfast with Minnie and friends.
