Sure, but in my specific context, "traveling" doesn't mean what you said, really.
There are directions in which going 2 hours from my door would get me to . . . one of the nearer satellite communities of the CMA/greater city in which I live, which might be different, but not different enough to be worth the hassle. (Yes, I know people who commute 2 hours each way for work.) That's partly "Canada is huge," partly "Canada has a famously rough winter that can easily double travel times," and partly "the Montréal area, specifically, has poor roads and closed lanes even at the best of times, as well as unreliable regional rail."
If I want to get out of, say, my country, and go somewhere I won't see people from home or hear mainly English or French around me, I must board a plane that costs much more than a road or rail trip, and then fly for at least 4 1/2 hours and probably for more like 6 1/2 to 7 hours. I'll need a passport and perhaps a visa. I'd formerly have had less strict standards and included, say, Portland, San Francisco, or LA . . . but the recent political situation between Canada and the U.S.A. militates against that.
Globally, something like that is normal – the EU perspective is skewed.
Let's assume, then, that when I am writing here, "tango travel" means getting on a plane in, say, Montréal or Toronto or New York City or LA, and flying for most of a day – at considerable expense – to somewhere like Paris or Berlin. Where, being a North American with very low odds of knowing anybody, I will have to pay for a costly hotel to stay in. (It seems to me that "stay with friends, or even just acquaintances, to save money" is more of a North American value than a European one, but I could be wrong.)
If you count "Getting into a car and driving for a few hours to the next city down the highway," my partner and I have already done that many times. By Canadian standards, that isn't "traveling"; depending on the destination, we'd still be on local health insurance and could take an on-demand CommunAuto rental and just drop it off in the street! By Canadian tango standards, up to half of the people we'd encounter would be people we'd see here. (One time, it was "all the people but this one guy.")
This is alien to my life, too.
Were I to travel to dance – in the sense above or even just the local sense – it would be with my long-term life and dance partner. I've lived with her, shared wins and losses with her, and traveled with her for years and years, so I know we're compatible and that I can rely on her. I wouldn't need to travel to some tango event to find that out.
Due to us being a couple, if I said to her tomorrow, "I am going to travel abroad with another person to dance with her at this event," I'd put a "long-term partner," "live with her," "rely on her," etc. at risk. Maybe it's just our values, maybe it's Canadian values in general, or maybe it's something else . . . but traveling with someone who could be mistaken for your life partner – as a tango partner could easily be, at least where I live – isn't generally done. It would look like an affair, and most people in my life would certainly treat it as one.
I've had many offers to travel for tango with women who are not my life partner. Some have even offered me a prepaid place that I could've claimed by saying nothing more than "yes." However, by the standards of my relationship, culture, region, and whatnot, having said "yes" would have been the same as telling my partner that I'm off to have a romantic adventure. For people with full-time partners, "tango partner = life partner" is usual here, and those in that situation travel only with their life partner, whether the reason is tango or something else.
So, let's also assume that when I am writing here, "tango travel with a dance partner": means "travel with a life partner."
