Which of the following is NOT mentioned as the thing included in your list?

When you’re preparing for a holiday, you should first and foremost make a list of all the documents you’ll need. Your list should include the following things: passport -- make sure that this is current, visa -- check the visa requirements for the countries you’re visiting, tickets, travel insurance certificate, foreign currency anti traveler’s cheques. You’ll also need your driving licence if you plan to rent a car.
   Tip1: It’s vital to arrange travel insurance for your trip and your travel agent will probably offer it to you when you hook. If you lose your baggage or your money, or if you need medical attention while you’re away, your travel insurance will help to meet the costs. But be warned, if you’re planning a skiing holiday you’ll have to pay an additional insurance premium.
   Tip2: It’s not a good idea to travel with large amounts of cash. Only carry the amount you’ll need for day-to-day expenses such as taxis, bus fares, and food. Traveler’s cheques are a far safer way of carrying money round because you can get a refund if you lose them or if they’re stolen. You’ll need to order them from your bank in advance, and remember that banks abroad will charge a small commission when you cash them.
   Tip3: If you’re hoping to do some sightseeing, it’s best to buy a guidebook before you go, otherwise you may have to pay for something which is badly translated and barely understandable. If you don’t speak the language, take a phrase book as well -- it could be very useful if you get into difficulties and may help to break the ice with the locals.
   Tip4: When you’re packing, be careful to stick to the airline’s baggage allowance or you’ll have to pay for the excess weight when you check in. Don’t put aerosol sprays in your case, and make sure any sharp objects, like scissors, are carefully wrapped. Two useful pieces of equipment to take with you are an all-purpose adaptor and a light traveling iron.
   Tip5: If you are flying a long distance, there are a few things you can do to reduce the effects of jet-lag. Before you leave, try to adapt your eating and sleeping habits to the time zone you are traveling to. If you eat small amounts through the day, and try to sleep for short periods, it may be helpful. During the flight, walk around the cabin from time to time and drink plenty of water to cut down dehydration which causes exhaustion.
