We just returned from a family trip - 23 people stayed in the house and it was a great set-up for us. The house is part of a relatively new development that includes a clubhouse/water park area with concierge service. We were fortunate to have good weather and a chance to use the water park. The clubhouse area also has a restaurant, fitness center, etc, but we didn't use those during our stay. Several people did use the sand volleyball courts at the clubhouse.
Pros:
Lots of room to spread out; two separate TV viewing rooms (in addition to a TV in each bedroom)
Comfortable beds
Nicely decorated
Each bedroom has it's own bathroom for extra privacy
Pool and hot tub in backyard
Access to the resort water park and other amenities, such as shuttles to the theme parks
Kitchen has two large refrigerators, two dishwashers, plenty of dishes, and a large pantry area
A couple of cons:
Not much cooking equipment available. We ate the majority of our meals at the house and had a hard time coordinating some of it. For a house that big, we thought it should have things like extra-large cooking pots, a large slow cooker, measuring cups, etc. Also, an extra coffee pot or a Keurig-type machine in addition to the regular pot would be helpful. If you don't plan to eat there very often, then it might not matter but it's something to keep in mind.
The pool and hot tub heater were tricky to figure out and we ended up having the management company come out more than once. A few other minor items, too, like needing more pool towels. I will say that the management company was fairly responsive to our concerns and got everything worked out eventually. My advice would be to take a few minutes your first day and make sure everything works, is stocked, etc, so issues can get fixed early.
Overall, we had a great experience and would recommend this property.
