We will be traveling to Italy. One week land tour on our own and one week cruise. Mom is 73, kids are 11,9,7. I am hoping to do carry on luggages only but I have not see posts in luggage recommendation for kids and seniors. Mom can't carry backpack luggage. Maybe my husband and I can split her stuff in our packs and the kids carry their own? Or is there a good light weight one for seniors that is easy to work with? How about kids luggages? What do you recommend?
