Yikes!! Never had that happen to me and, frankly, I might flat-out oppose the policy and risk whatever consequences that entailed. I'd probably first go the route of staying in a lower-cost hotel or otherwise trying to keep travel costs manageable, but I don't see any way I'd room with a coworker in a standard hotel room. If the company would fire an employee for that, then it says all I need to know about that company.

When I was single and in my 20's, I worked on long-term projects where we'd share a 2-bedroom corporate apartment (always 2 people, 2 bedrooms, 2 bathrooms), but when we did side trips, we always booked our own hotel rooms.
