Join the "Back to Back" Club
Members of the "B2B Club" have done two consecutive tours "back to back".
All it really takes is getting yourself between the two consecutive tours. For the most logical pairings, there is one day between tours to allow for connecting travel. Flights in Europe and Asia are relatively inexpensive as compared to the flight to get there from the United States so, if you have the time to do a couple tours back to back, it is an economical way to convert your tour into a longer adventure.
Based on the schedule the most logical pairings for 2007 are:
Spring: Corsica - Slovenia
Fall: Slovenia - Spain
Winter: Vietnam - Laos
