I am saving up for taking a rtw trip for next year sometime. So far what I have come up so far as a route to take. I'm going to get a plane ticket leaving from Clevland or New York to Reykjavik then to london. Then use a eurail pass and bum around through as many European countries as I can for 3 months. I want to see spain, prague, paris, italy, etc or as much as I can within 3 months and try to spend a week in each country so that would be 12 countries in 3 months. Then at the end of 3 months return to london and travel overland to hanoi via train following this route it will take me from london into moscow and to beijing via mongolia. From beijing I can travel to shanghai, and then to Hanoi to Vientiane. From there fly to bangkok. Then fly to hong kong, then honolulu to San diego and then make my way back to ohio. The rtw ticket came out to be between $1444.00 - $1732.00 on the trip planner program on air treks. The eurail pass is $1075 I turn 25 this may hopefully I will be able to make this trip before I am 26 and I can qualify for a youth eurail pass. The trains will probably run about $520.00 according to the website that I was looking at. So that is about $3400 in transportation. I am planning on having at least $10- $12,000 saved for my trip. So does this sound feasible on my budget? Am I missing anything or any real good places. Would I be better foregoing the RTW ticket? So let me know what you all think. I want to be gone as long as possible. I would like to be gone for at least 6 months. When I get back to the states I plan on seeing as much of out west as I can I will probably head up north towards alaska and snowboard through the winter. Then I guess it woud be back to the normal routine of working until I can make another trip or I will have to finish up college or something.
