My family of five took a 2+ week trip to eastern Europe this past summer. We were only allowed to bring backpacks. We decided on this model based on its size and ability to add a daypack to it. I was able to pack more than enough clothes (& 2 prs of shoes) and still have room for souvenirs. I like the easy access to the different compartments and also the ability to lock all of them together by aligning all the zippers and threading a travel cable-lock through them. They were easy to carry and made our lives so much easier boarding trains & planes! No complaints!
