My DD is a girl scout,too. She loves to sing, dance, and make crafts. She is cheerleading and gymnastics. It sounds like she will have a lot in commom with both of your DDs. Your DD9 will be in the Lab with my DD since 8-9 are together.
My kids have been to WDW twice. But, they would rather cruise (which is ok with us)
Also will have a DNephew 10 on the cruise, the same age as your son

Our children love DW and DL, but have never been on a cruise. Hopefully, they will like it as much as yours
