Most people would love to go on a world cruise and see the world. It would be terrific to be able to see all the things that our world has to offer. From monuments to mountains to kangaroos, there is so much that we are yet to see. However, the question is, will we be able to see it all? Often enough, we are unable to do much of the things that we hope to because we are on a budget. Even if we manage to get rooms in one of the top-end hotels, chances are that for the rest of the year we will be scrimping on necessities like cornflakes.
Despite that, traveling on a budget can be a lot of fun. At least you are going to the places that you have been dreaming of for so very long. So many people never get to do that. I agree that you may not be able to shop till you drop. However, you must agree with me that the experiences that you have and the memories that you gain are worth far more than some over-priced souvenirs any day. So even if you are traveling on a tight budget, try not to grumble. At least you are getting to go on a vacation.
Of course, even as you set out to see the world, make sure that you are well prepared for all the eventualities. Carry enough cash...
