The Trackers really do all these places they vacation a disservice by featuring them on their vlogs. I certainly wouldn't want to take a cruise knowing that every time these doofus travel they catch a disease, whether they bring it with them or catch it there doesn't matter. Both look incredibly bad to consumers.
If I had a hotel and Tim asked if he could be hosted at it in exchange for a vlog review I'd quickly respond with a "No thanks, but could you review my competitor across the street there?"
