DH and I are taking our 2 boys (18 & 20) to Europe. We will spend time with family in Scandinavia and travel south through Belgium to Normandy, then Le Mans, Paris, maybe the Alps, and then north to Copenhagen. I think I've thought of everything related to weather, etc. but maybe some of you could share your experiences related to packing what is really necessary. I tend to want to pack everything I could possible need.
