Thanks for the info Matt. I would definitely recommend that each and every one of you that have layovers in various hotels around the globe invest in one of those portable locks. In the 8 years that I have been flying, I have been woken up twice where someone has walked into my room. One apologised saying they had obviously been given the wrong room number and key by reception, the other person did a runner, obviously intending to go into my room but not expecting me to be there. I remember checking into a hotel in Oman once and walking in on a couple in bed
. I was given the wrong key and room number. It happens alot and I know of other people that it has happened to aswell. Rather be safe than sorry!
