Very sensible advice, sixmile, well done!!
I want to stress the point of not disclosing your hotel name and details to
anybody , passengers or people you meet overseas. This is also valid for domestic nightstops, I could tell a few stories of girls (and boys) being disturbed (and even worse) by angry passengers or passengers/local people with not very good intentions in the hotels where we were staying as crew. (Newcastle layover anyone?)
ALWAYS say you don't really know - at the end of the day when you go from country to country and sleep in different hotels every duty you do, it is understandable if you forget where you're going and where you're staying. Blame it on the jetset life!!!
