http://roadscholar.org which was formerly known as “Elderhostel”, plans for learning experiences from your home state to the other side of the world. These are in depth experiences, often with a focus on special interests, and in some cases are quite frugal. The details are all laid out for you and include information on the activity level and accommodations. People who have experienced these trips are quite enthusiastic and many return for other adventures throughout their senior years. All ages are welcome and you might also want to check out trips designed for mixed generations, such as grandparent and grandchild.
