This sounds like a great way to make the non-mainstream places mainstream, especially when the "influencers" rush to visit all the little known places for clout XD

In all seriousness though it sounds like a great idea, my mum found this guy that does small group food and wine/beer tours and he does some touristy areas mixed in with some more little out of the way places that only locals know about, and they were lots of fun. If you're into that kind of thing I think I'd just be sending you to him XP

Planning on starting another project? :D
