I've not stayed at that resort but it looks nice. Also doesn't look to be "too" far from town.
Had friends from MI stay there (I believe the same resort) on their way to winter with us in FL and they really liked it - especially the proximity to the water. Went to visit their daughter. They had 2 young grandsons and I suggested they take them to the Rain Forest Café in town. They did and they said the children loved it. If you have kids you might want to try it out as well. If you can, try to go after sundown and let them see the "volcano" erupt with all the fire, smoke and roar
