Wow .... I feel scolded for being concerned about spending a lot of money with an unknown company -- didn't realize that was "demanding". My concern was that I was going to be booked on some unknown airline where the passengers could take turns driving the plane.
At any rate - we took the South of France tour and had an absolutely fabulous time. As an interesting side conversation - we took off from NYC the day after the blackout. Our flight was cancelled but Viking handled everything -- the agents were simply great. Now that Viking is not unknown - I can't wait to take another tour. Looks like my biggest problem now is deciding where in the world to go!!! :-)
