American travelers
We cater exclusively to American travelers: English is the only language used during tours and presentations, and your trip is tailored to an American perspective, from experiences to accommodations to dining—which include regional specialties.
I’m fine with English language, but I like to have the perspectives of people from other English speaking countries, including the Brits, the Aussies, and my own Canadians. I don’t want a trip tailored to an American perspective.
