i see that Gutsy Women Travel is also a division of Grand Circle, which also does OAT small groups Overseas Adventure Travel....there is also a singles travel company out of california, but it sounds like OP is not looking for group trips....many people like to rent a car and drive around on their own....i would be willing to go as a passenger but i will not volunteer to drive around europe

nor do i enjoy rushing to catch trains... i personally like the camaraderie and care free feel of a group tour.
