We are leaving on Aug 13 for WDW, the trip has been paid in full. I will be traveling with my husband, nephew and neice. When I booked the trip I had the kids as 17 and 14. Not thinking that my nephew turned 18 on 7/14. What should I do, let them know that he is now 18 and if so do I call or wait until we get to the resort? Or since I booked and paid for the trip when he was 17 not worry about it? I do know the charge will be $25/night @ 7 nights.
