Totally ok as long as he doesn't partake in the group outings

Not ok but if no one finds out...

Definitely something that should be discussed and approved by group guide

I'll be traveling to Europe in August. I'll be part of an organized group tour. I have a friend that lives in the country I'll be visiting, but is from outside the city I'll be in. We would like to meet up. Would I get in trouble for allowing him to share my room if he's not part of the group?

Serious answers only, and especially if you're sure of the answer as opposed to guessing.
