This isn't really specifically about RS tours, but about tours in general.
I've discovered a pet peeve that was a real problem on a recent tour I took, and I'm wondering if you have experienced the same thing, and what, if anything, you've done about it.
Some of the people on the tour insisted on comparing everything we saw and did with how it is back home. In some cases, it was asking questions like, "In the US, we have {insert US thing}; do you have that here?" This is pretty innocuous if it's a quick one-liner, but sometimes it got into a detailed description of things like the US healthcare system or the US banking system or US traffic laws.
Worse, much worse, were people who insisted on describing, in excrutiating detail, how things are in the US, sometimes as if the tour guide has never heard of such things, and sometimes dominating the time we have to ask questions or hear and learn from the guide. For example, in Vietnam, one woman from upstate New York spent about ten minutes describing the Woodstock festival to our tourguide. Afterwards, I pulled her aside and said, as nicely as possible, "I didn't come all the way to Vietnam to learn about things in the US. I came to listen and learn about Vietnam from people here." But it didn't get any better. I talked to the guide about it, and he said he was aware (he'd already heard about it from a guide in a previous destination). But he didn't really know how to put a stop to it.
Have you encountered this kind of thing? Any suggestions on how to turn it off?
