Just a word of warning to anyone who thinks safes in hotel rooms are actually secure, if you forget the number you set when you locked it, virtually any staff member knows the procedure to open it.
Therefore this knowledge is only as safe as the integrity of anyone who has worked in a hotel (and their friends)
My advise, either give your valuables to the hotel manager to put in his safe or use a safety deposit box if available.
Or try not to have too large an amount of cash or gold.
safe travels everyone
