The unit itself was really, really nice - 3 bedrooms (two queen beds, king bed in master and each with its own bathroom), very nicely decorated and updated, beautiful open view of the Gulf, washer and dryer, etc . I would give the unit 4.8 stars, but I am giving our "Stay" 4 stars for the following reasons:
1. This property is isolated from the other resort-style properties (e.g. Cinnamon Shore) with no beach access via golf cart. While there is a very nice boardwalk going from the pool to the beach, it's for pedestrians only.
2. One of the primary means of travel once you're on Mustang Island is golf cart. You can drive a car on the beach and park there with a parking permit, but tons of people drive golf carts on the beach and then back to their condo via wide boardwalks that are property-specific, and it's not possible to do this at Grand Caribbean and also keep the golf cart at your condo overnight. Golf carts cannot be driven on the island highway that connects all properties - it's illegal, but would be lunacy to drive a golf cart on that 2-lane highway.
3. The condo owners were very friendly and communicative ahead of the trip, providing tips and guidance. I did not talk to property management.
4. We had teenagers with us who had friends staying at Cinnamon Shore north. It's about 1/2 mile north on Hwy 361. My kids spent almost the entire time there because of everything available to do and LOTS of younger teens from other places. Cinn Shore also had a heated swimming pool.
5. There was active construction of a new boardwalk right next to our unit which made for lots of noise and vibration while they installed the support beams.
6. The weather was not great. While we did get a couple of sunny days, it was still cool and too windy to fish or enjoy the Gulf. The last two days were miserable with 50F temps, gail winds and misty or overcast all day.
7. I couldn't find a grill for grilling chicken or burgers. The property should add a couple near the pool.
