I am looking to buy either Rick Steves' Convertible Carry-On or the 21-inch Roll Aboard for my 2 week trip to Italy and wanted some opinions. I am not sure which one will be the best and most comfortable for me. I am short at just under 5' 1" and also have a short torso, so I worry that the Carry-on might not sit comfortably on my back. I typically prefer backpacks to shoulder bags because I like having the weight evenly distributed. The Roll-Aboard looks nice and lighter than similar sized rolling luggage that I already own. We plan to travel by train from Rome to Venice to Florence back to Rome.
Any advice? Thanks!
