When traveling alone or in a country you are not familiar with, carry two door stops and a roll of Sellotape, 1.Door stops are used on all doors that open into your room, 2. You place a strip of Sellotape at the top and bottom, but in the middle of the sliding patio doors. If you in a 4 star or above leave valuables in there safe, and never leave you suitcase on locked when out the room, remember what you consider to have little or no value may have great value to the maid/gardener or maintenance man.
