I'll throw in a comment here, CC is unique, that's what makes it so special to most.
The island stops do have beaches that may be more beautiful, there are certainly other beautiful beach locations in the Caribbean to travel to, but CC is private, Disney themed, activities geared towards DCL passengers, convenient access from the ship, it's a private paradise to some, maybe lackluster and non eventful to others.
There is a bit of hype leading up to it if it's your first visit and you read these boards, so I can certainly see how you might have a disappointing experience. Just take it for what it is, Disney's attempt to create a quiet, private, relaxing environment away from reality and the outside world for its passengers, a unique way to end a Magical cruise.

So, I was very thankful for
We didn't make DSs stay all day; we all did the Banana Boat ride together and swam a little together at the family beach, but then we let DSs head back to the ship on their own (They were 16 1/2 and 13 1/2 at the time). Then DH and I enjoyed more time at the beach with DSIL and DBIL. So, I was very happy to have this built-in beach day because otherwise, we didn't spend any time at any other beach. (Spent a lot of time at the adults only pool though, and DH and I absolutely LOVED it!)
