Here are a few tips on packing for a summer of travel.
Most people prefer a backpack because it is easier to handle than a suitcase.
It leaves your hands free, you can easily hoist it onto a luggage rack, and you don't have to drag it over cobblestone streets. An internal frame pack with straps that can be concealed is ideal. Local camping and sporting goods stores carry a variety of styles, and their staff can help you select one to meet your needs. Additionally, it is always convenient to have a backpack with a removable daypack for taking with you while you wander around the city. Keep your most important documents in a money belt or neck pouch worn underneath your clothing at all times.
