For the first time in the 10 Days series, you can link travel tiles!  Th is truly the most unique element in this new addition to the 10 Days series.  I've had trips where I have 3-4 ocean liners all linked together before I even touch land again.  I like that.  I have also learned a lot about geography in central and south America.  Very fun and a nice new way to learn geography of the western hemisphere.  Something severely lacking in students knowledge base today.
