With 500 million Local Guides, I’m afraid this will not work. I think it needs to be more individualized and based on specific and mutual interests.
Not that my visit to India is representative or something special, but I carefully selected two LGs in India based on their interests and engagement in drawing roads and Maps photography.
Feel free to check out the following posts, and I think you will understand what I mean:

But please take this only as my personal opinion/interest. Acting as a tourist guide in Copenhagen is not as interesting as mutually exchanging specific Maps related skills in a meetup. Both @TorM and @JanVanHaver previously visited me, and we dived deep into Maps photography and Maps editing as two nerds exchanging practical tips and methods.
