Been there three times. Very nice resort, good dining. Not a lot around there to do, but if you have a car and are willing to drive some, there's shopping, museums and nature centers nearby. The beach is gorgeous and you can't beat the view. Try and get an ocean view room if you stay in the inn.
Overall, it's a great place to unwind and just relax. You can wander the beach, rent bikes, play shuffleboard or putt-putt at the resort, swim or sun pool-side and that's about it. There is also a spa that we had a couples massage at which was great, but like all Disney spas-pricey.
Go and enjoy. Just don't expect to be overwhelmed with things to do at the resort.
