Where does your experience conflict with what we have learned?
I thought you said that you noticed if a guest had a lot of luggage. I do not see a conflict there.
All I'm saying or commenting on is your cavalier attitude to dismiss. Mandalay has cameras all over and let's say suppose they don't have any in the hallways, but I dang well guarantee you they have one at the elevator entrance and especially at the service elevator, to prevent guest or employee theft.
Why haven't those videos been released after 2 weeks, things that make you go hmmm, and you dismiss such as "conspiracy"
