The price of holidays can fluctuate a great deal throughout the year, so you can save a lot if you are flexible with your travel dates and avoid peak holiday times. It can be also cheaper if you book well in advance. Before your departure, make sure you get as much information about your destination as you can. Find out if you require any special visas or permits to travel there. Think about spending money as well. Will you be able to access your own money easily enough or will you need to take cash with you? Think about eating larger lunches and smaller evening meals to help your money go further, as lunch is generally cheaper. Make sure that you keep sufficient identification with you at all times. It may also help to email a copy of your passport details to yourself, in case it is lost or stolen. Label your suitcases clearly so that they can be easily identified as yours.
