During sim, one of my sim instructors got bed bugs in his hotel room. On a trip, Captain got bed bugs in his room on one of our overnights... I've found one myself in a room, but fortunately none were tracked home with me or to other hotels. I've had another friend get bed bugs as well. That's 4 instances I've seen/heard of in less than a year. They happen. Always check your sheets before just crawling into bed. It takes like 10 seconds...
