Im staying at the Marriott Grande Dunes the week of Sept 22. Although I've been there before, its been with my buddies. This time I'm going with the wife, 20 month old son, and in-laws. Ill be there for a week so I have plenty of time to fill. So does anyone have any suggestions on some "must do's". Im not the type to just sit around for a week, I need some adventure. Any help would be greatly appreciatted!!
