What's the most appropriate term? "Bus Guide" or "Guide bus" or "bus tour guide" ? Some who shows people Paris or Amsterdam or New York ect.. in a coach?
In my experience, the word "guide" is far, far more common, and I would be inclined to use the term Tour Bus Guide in response to the original post. (Tour Bus being a compound noun functioning as an adjective to describe the guide, if you follow me...).
Actually, the more I think about it, is the word "bus" even necessary? Couldn't you just say Tour Guide?
It would be the same if I called and asked to speak to the driver for XYZ Tours. I would not have to define that this driver was a bus driver.
