We will be at WDW from Aug. 9-14 with 3 teens--15, 18, and 20. This is will be our 4th visit, but we have not been there in 10 years. My son (20) says no one his age will be there---going somewhat under protest, but will spend a lot of time at the pools. We are at the Yacht Club. Anyone have any specific suggestions for us? We will do MK, MGM and Epcot--perhaps night activities? Thanks.
