I would say test them out at home first. Sometimes the "fun" of having your own suitcase doesn't last. When kids are tired they seldom cooperate. Those cute carryon bags become a nuisance quickly. After saying that, I also know some kids are very responsible and really want to take care of their own stuff. It just depends on their personality. Also, if you arrive at night, you'll need to pack things for bedtime and carry it with you. We had a total meltdown to deal with when our luggage didn't arrive until 11 pm.
