And here I usually have a stash of Marriott keys that forget to turn in and occasionally drop off at another hotel rather than throw them into the waste stream. You know the darker gray with the mag stripe, the lighter gray with the mag stripe, no mag stripe, the Renn keys.
I had no idea I could get a $1 for them or that they got me anywhere in the hotel other than my room and the concierge lounge during my stay according to the code. Have I been missing something?
