10/10 Excellent
"The rooms & halls were clean, the indoor/outdoor pool was unique and well maintained, the front desk staff were friendly and helpful! We requested connecting rooms in the initial reservation, and they honored our request. The breakfast staff (seemed to be just one lady) worked hard to keep things stocked, but it got quite busy several times and by our third morning, coffee & creamer & juice were running low. The breakfast options were exactly the same every day, so a little repetitive. And the breakfast area floor needed a good washing. Overall, my family & I would stay here again."
