Marriott is considered a "soft sell" in the t/s industry.
My family loves Horizons. Our kids love the 2 zero entry pools. The pirate ship has interactive water canons. There is a turtle pool for the younger ones. The ship also has slides on 3 sides of it.
There is a small water park on site. There are alot of fun activities for kids. They are getting more activities for the older kids. Our kids love ALL the activities.
The 18 hole putt putt course is alot of fun.
