Hello! I am going away for 4 days with two children in the summer. We are traveling by train to the coast having a short break (hotel). We then return home via London, spending one night going to museums, then travelling by train home. This will involve getting on and off trains and traveling on the underground, so I need both hands free and will be using escalators. Thus meaning my usual wheely suitcase is not practical. .
I would like to buy a nice rucksack big enough for a few days clothes but not an ugly backpacker style bag. Does anyone have any suggestions please? Not much of an idea of budget, but cheaper is better!
