The Marriott Vacation Club Willow Ridge Lodge is a wonderful family destination. They have swimming pools for all ages. From the nice kid pool to the large pool for family there is plenty to do at this resort. The views from the upper floors can lookout onto the surrounding countryside or overlook the pool. They have a nice fitness center and even an indoor pool and Jacuzzi for the winter months so you can still enjoy the water.
You are close to all the tourist locations so it is easy to see a show or enjoy a hike even while being inside the city limits.
