Can anyone recommend a great/decent hotel in eagle beach area?
I would agree that the Bucuti is the nicest and is just for 18 plus. I would not really call the Manchebo a family destination as they only allow 2 in a room as well but they do allow kids. Even though kids are allowed at Manchebo you won't see many because they only allow 2 in a room.
If you have a family I would also check out the Costa Linda for the additional space it offers.
ArubaAmy nailed it.
What about renaissance? What are the downsides?
Just if you want to be right on a beach, you are not. But the boat ride to the private island is fun.
