I travel a lot and have been torn up only once, because I didn't use my own advice. At cheap hotels in Asia, there are many hotels and hostels that you should check out for expensive items at the front desk, but if you research them, many do not have a safe. I personally think that using the front desk shows you as a person who has a lot to lose and makes you a potential target. I gave you an envelope where I was staying and you were going to put it in and it was safe, don't think!
So if you are staying in cheap hotels, hostels or serviced apartments, there are very simple and inexpensive things you can do to protect yourself against road damage. The biggest thing, remember to pack your brain, think about your safety, and think about it before you hit the road.
Bring a few small locks. They should only be strong enough to cause damage if removed. This will keep the servants honest. If you have the cost of cable and bike locks, you can do a lot with that combination, such as a wardrobe and drawer, to lock them down and give yourself little room for expensive camera bags, smartphones and other expensive electronics. Give a price. Otherwise you can lock your bag or luggage and then lock it to a piece of large furniture.
I don't recommend hiding money in rooms, but sometimes this will be your best option. The top is better than the bottom, and inside the machinery is where most people will not normally go for basic search. I already have things hidden in the fans, as well as in the air conditioners and under the TV.
What you can bring with no space or weight, and at almost no cost, is the low-voltage connections that electricity uses. Some airlines in Asia are now delivering mail when checking their bags, one idea is to use it to lock your bag and then tap the extra bar for airport security to search after Use your bag again. The United States of America these days.
In some of the poorer countries I've seen it with high poles coming into the room and pulling bags and clothes out the windows, so make sure the windows are closed and you have valuables so you can't He saw them from windows. I once saw a detour there and then we reached a room 10 minutes away with the occupants of the day!
Good luck on the road!
