I know share your concerns that we are going to spend all of our time traveling! I think we are going to try and focus on a single region. We still have alot to figure out. Thanks so much for your help!

but with cheap flights you could easily combined in-depth looks at two far-removed regions - like France-Spain and fly to Greece, flying home from there after landing maybe in Paris.

Just that constant moving around inside a certain region can be tiring and let you see little of the places you move between.
