Hey..welcome to the boards!!! I wish I was more thought out like you are. Starting to save now is a great plan. The amount you want to save of course depends on how long you want to go. Most people would say that $75 a day is an average amount to plan for, but since you have time, and because of that devil called inflation, maybe you should shoot for $100, but that is your choice. Also, plan in airfare, rail pass, and bus fees. This site has a ton of info for you and everyone is super friendly as well. Good luck on your planning!
