One huge gap I see between Euro and American tourists is that the Euro seems genuinely interested in seeing ordinary life in small town America whereas the American bΓΌrger really only ever stays within a capitol or around the main sites.
Not many Americans itching to pass through BesanΓ§on, ΕΓ³dΕΊ, Kiel, or Ipswich, but Euros are completely gobsmacked by Fairhope, Chattanooga, Middlefield, Bowling Green, and Ocean City.
