Well, the places look quite great tbh, even when 'conducted' lol. And I understand that in some places/cases, there'll be no tour with conducted ones. I'm actually fine with that. What I was referring to in my post was actually a very strict and rigid version of what you had in mind.
In Bangladesh, these tours are almost like chores. Like a usual day at the office. I think would get even more stressed if I go again on a trip like that. 🙁
Yes, of course, I understand that. What a marginal business model and can be improved so easily.
