I did! I went to America (California coast, Hawaii, New York, Miami), Dominican Republic (popped down to see my friend get married), New Zealand, Australia and Thailand. I thoroughly enjoyed it! I spent about 2 years away, a year of that in Oz. Tips- read up on the hostels, do not do a mixed dorm, i did that a few times and to be surrounded by snoring men was not my idea of fun! I did not plan my trip before i went, i used to go to the train station see where the trains were going and decide from there! It was the best thing i have ever done, but i dont think i could do it again, not now, too old, too many expectations of hotel cleanliness etc! x
