Traveled pretty regularly with work short stays all the time. I always settled up at check in and got a receipt then so I could get in my truck and go dark and early leaving the card key in the room. 95% of the hotels had no problem with this most preferred it, less work for them. The few that were all 1980s about it said we'll have to disable your phone then so long distances calls couldn't be made. lol when's the las time anyone used a hotel phone?
