We just returned from our stay there and it was perfect! We decided to go Sun-Wed because wanted to avoid the bachelor/bachelorette crowds (we had our 6 year old daughter with us) but needed it to not be wild with kids (that was for my husbands sanity). It was the perfect mix of people.
The staff was amazing no matter where we were in the hotel and my daughter loved how our housekeeper always lined up her stuffed buddies on her bed everyday. The food was great everywhere we ate and the grounds were gorgeous.
The summer is hot but the price is definitely right since I don't know if we would pay the on-season rates (you're in the pool the whole time anyway). We will be going back for future summer vacations, for sure.
