My best luggage advice is go light! Wheeled or backpack but make sure everything does double-duty. Clothing you can layer is great. I think Linda has her list of essentials online in Travelzine and there are other lists. Look in Google DIRECTORY for some good links. http://makeashorterlink.com/?H22E22262

Count on handwashing some or at least line drying. Laundromats are expensive in Europe. Accommodation sometimes provides a washer but no dryer. Anyways, I don't bring enough clothes to last a week, just a few days. I test my newer clothes before I pack them to see how they look after they have been washed in the sink and hung to dry. If they are unwearable, I don't bring them.

Length of trip isn't really relevant but climate changes are.

Have a great time!
