our family chose to stay there instead of on-site at disney and we were very glad we did. The pool was never crowded. We could swim to 1:00am. The grotto and waterslide was huge. There are also jacuzzies hidden in nooks and crannies around, but I didn't spend anytime in them 'cause there were alway "kissing couples" in them. Nothing lewd, just affectionate people. The fitness facility had a glass wall on the side that face the pool. It looked nice, but I did not get a chance to check out.
You will love the food at the Hemmingway if you choose to eat there--we did. I recommend the grouper. The restaurants do tend to be a bit pricey, so we ate most of our meals with PS at disney. My son loved Camp Hyatt on the days we were not at the parks and I loved the beachside lake and hiking trails. I do not golf, so I did not try the course, but I did go horseback riding. As far as kids are concerned, bike riding, sand castle building contests and crafts were just some of the activities kids enjoyed at camp. The also have game room and babysitting services if you need it. It came in handy when we spent an adult evening at Pleasure Island. The resort is gorgeous and I know you will love it. The atruim is breath-taking and they have a piano bar where the piano looks as if its suspended in the middle of a pond in the atrium area.
We had club level with breakfast in the lounge and afternoon cocktails and food. Our suite was beautiful, very clean with a stocked fridge ( which we avoided because of the prices), and turn-down service. Chocolates and towel animals every night!! We also had an excellent view of Disney from our suite. The service was excellent and they provided shuttle to the parks. We opted to go for a car rental so we could have more flexibility. There is an Enterprise onsite by the way.
Trivia note: A large number of people we met there were European and Australian which made our trip more interesting and adventurous.
Btw, we were there in the second week of July.
