1.) Always tell someone else such as a parent or friend where you are going, the address and number of the hotel/hostel or event or whatever that you have scheduled. Plans can and will change but it is always a smart decision to tell people who you trust your whereabouts.
2.) Scan all important documents, email them to yourself and a parent or someone you trust. These include your passport, visas, travel insurance as well as hotel reservations, plane and/or train tickets, etc. That way, if you lost something, there is proof that it did exist. I had a situation when I was going back to Auckland from Brisbane and I forgot to bring my visa papers but had them emailed to me. The airline let me sign in and print off my visa from the email link and I was able to go back without more hassle!
3.) Always look back before you leave. Right before exiting a resturant or museum, take a look at what you have with you, make sure you have everything and just in case, look back to where you sat. It’s a common mistake that can be avoidable.
4.) Speaking of leaving something behind, guys, put your wallets in your front pockets or in the inside pocket of your jacket. Ladies, have your purse over your shoulder with the opening facing you. These are simple ways to make sure you don’t get pickpocketed. I even wear my backpack with it’s zippers facing my back so that no one can try and get in. Better to be safe than sorry!
5.) And for heaven’s sake, always keep your bags in front of you, never put them behind you, hanging from the chair. You are just asking to be robbed! So keep them on your lap at all times or wrap the strap around your leg so that no one can get away with them but yourself.
6.) Diversify where you put your money and credit cards. Do not put them all in one wallet but put some hidden in your luggage and the rest with you. That way if you lost or were robbed of one credit card, you have a back up.
