Fantastic! She will love it...as will you! We did the same cruise last year and loved every minute of it.
We will be at the parks first (Beach Club) then the cruise, then back to the parks (Boardwalk hotel) We are renting a car, because we found that the transportation from the hotel didn't get us to the ship until 2:30, not much time to join the bon voyage party, which your daughter will absolutely love!
If you have any questions, please let me know!
