Traveling around the world may be the last thing on your mind if you are looking for a budget holiday. However, bear in mind that once you are on the move, the incremental cost of an extra stop will not be as large as the cost of traveling that destination from home on a different occasion.
Many operators will also often offer a discount for travelers who want to make several stops, so if you really fancy a couple of nights en-route, enquire about options. You may be pleasantly surprised.
Another possible option is to simply book a one way ticket to your first destination, this will allow you the flexibility to decide when you want to travel on, and will also allow you to benefit from buying locally, which will almost invariably mean you get cheaper rate. One of the main disadvantages of this method is that you are in effect stranded and if you cannot find a cheap flight, you will have to buy one anyway! Immigration officers are also a little more fussy when it comes to admitting someone only with a one way ticket and no obvious onward plans.
