Whenever you arrive in any country, whether it be by boat, plane or whatever you are vulnerable. You have all your cash, cards, documents and anything else valuable on you right at that moment. It is even worse if you have never been there before and look like you haven't, there are always people who are willing to "help". Every precaution you take will help to avoid any potential problems. After all you do not want someone to "help" themselves to your belongings, when you have just arrived. Here are a few tips that should help.
Before leaving for your trip, try to get some prior information as to the rough layout of the airport where you will be arriving. This will help, to have a vague sense of where you should be going and where the taxis are located etc.
Whenever possible, especially in certain countries we recommend taking either the airport limousine, or a hotel pick up.
Never take a taxi that seems just to be hanging around, offering its services when there is a taxi queue available.
Try to keep your wallet and valuables safely secured in a handbag or in one of your hand luggage.
Change some money into the local currency before you depart. This gives you one less thing to worry about, and will stop you from pulling a large amount of money out at the airport arrivals.
Keep a small amount of this local currency, easily accessible in a pocket or something, and away from the majority of your well earned money. You will need sufficient for the ride into town, a tip (perhaps) and a little for unforeseen needs like toll ways or a bottle of water.
If you have not been able to find anything out about the airport that you are visiting then ask one of the airline staff, or the government tourism booth (if they have one at the airport) for some assistance, or tips on the best way of traveling.
Most countries really are very safe, but in others it is really very advisable to take to take as many precautions as possible. No matter what, the most important is that you have a great holiday.
