As a tourist/world traveler, I don't "play" with international regulations due to the small but significantly statistical chance that I'll get penalized heavily and made an example of. That can take some major adjustment at times. I wouldn't retire to Thailand, but I enjoyed my visit as a kid enough that I would consider vacationing with nic lozenges, but I wouldn't be thrilled about it.
At one point I was going to school X4 in California per year for a week at a time, and also being sent out to I forget where, exactly, but out of town where I client of mine had been sent to a "super special scary" residential facility and since I was her "therapist" and she had no family at all (CPS stuff) they flew me out a bunch of times and put me in non-smoking hotels, all that time at the airport, LOL. I was dual using at the time, which helped, slightly, but it was still a giant PITA. It's a lot easier to travel with all the restrictions when you *want* to, rather than doing it for work.
And, it's just never easy. There had always been a place in my life for the nic lozenge, but now that I'm not dual using, I would far rather vape, and I can go much longer between vapes if necessary.
I don't know how Costa Rica is for vaping, but I've visited twice and had WAAAYYY more fun there than in Thailand, though I was older, so there was more fun to be had, by me at any rate. I can't go back to Costa Rica though, I wasn't sober when I visited and they have some of the best (and strongest) beers in the universe....) For those of you who enjoy beer and vaping, it might be ideal? Not to mention the rainforests cloudforests, etc. Tons of amusement to be had in Costa Rica, when I went with my HS class, (my HS did a senior trip every year and fundraisers all through high school to pay for it) our class ignored the "Danger, don't go past this point" sign near the active volcano, and some of my pals were lighting cigs off lava-- we were idiots, there was a major explosion the next day---

Our tour bus almost plunged off a mountain, one hotel we were in was bedbuggy (LOL, we did not select a prime guide/tour service, we were kinda broke), and all kinds of misfortunes and misadventures happened. We had the *best time*.
That said, our class was one of *those* classes... Looked angelic, every member involved in something inappropriate.... We kind of ruined it for future classes as when the teachers and chaperones came back they also reviewed everything that happened with a less favorable outlook. A rule was reinstated where senior trips did not go out of the country. I felt bad about it, but only once I got a bit older....
