One of the many benefits of a vacation is relaxing! Sleeping in during those summer mornings and enjoying the sunset are all things that make memories to last a lifetime. Don't book yourself too tightly on your vacation to enjoy all of these more important things.
Plan your vacation around what you like to do, but include everyone in the groups likes and dislikes. If you like to ski and your spouse enjoys hiking, make sure that you either do your own things or you plan time to get both things into your vacation. Its all about sharing your time.
