I have a friend who is surprising her son, DIL, 4 year old granddaughter, and 13 (almost 14) year old grandson with a WDW trip at Christmas. They are going Spring Break time. She's asked my advice but I know granddaughter won't be able to ride some of the things 13 year old will want to and he probably isn't going to be into It's A Small World and Princess meet and greets. I suggested they split up at times. Someone go with GD with a fastpass to Frozen Ever After, and some go to Test Track with a fastpass, for example. However she doesn't want to split up. It's going to be busy and they are only doing 4 park days. I told her about rider swap but she doesn't think GD will be patient enough to wait for something that she can't do. Suggestions? Thanks in advance.
