And I guess "don't be followed to the hotel" would be a good rule to adhere to. Also, as said, good idea to disable any tracking abilities in your phone.
I've never heard of that. So, what are they supposed to do, wake you up in the middle of the night while you're sleeping just to check on you? You know many people work out of town and stay at hotels. Can you imagine working your ass off all day for like 12 hours and needing sleep only to be awakened in the wee hours of the morning? I would go off on them for doing that, maybe to the point of violence.
