Wonder if Casey's parents would be willing to adopt me so that I can go too?
You will be the youngest one aboard, Casey, but I wouldn't let that worry me. If you really enjoy seeing lots of new and exciting places, you will have a blast. Maybe you won't have young folks like yourself to mingle with onboard the ship, but I would imagine the thrill of traveling on such an exciting voyage would more than make up for it.
Go and have a blast. To be honest, I envy you.
