Linda and I will be departing on a 21-day small group tours to Paris, Normandy Invasion Beaches, Edinburgh and the Scottish Highlands. Everything, as usual, goes in our carry-on. We will take one suitcase each and a small backpack. We will take into consideration the weather, the terrain we will be walking on, the sites to be visited. 21 days is actually a short trip for us, we have gone on trips as long as 44 days with just a carry on. Look at the blog post to see how we pack and what we pack.
