Take the time to learn how to pack for your trip.
Your back, arms and neck will appreciate it! Remember that you will do a lot of walking with your bags and you should be able to lift them yourself without assistance, as help may not always be available. You may have lug bags over uneven walkways or carry them up stairs. You can learn to take less, look good and have everything you need. It just takes a bit of practice and self-control.
