So on May 29th I am setting off to travel the world for pretty much the first time, and by myself. I am 21 and am already a couple years into a career and decided it's not for me, so want to travel til hopefully next year before returning home to go back to uni. I will have saved about AUD $10,000, and this is the amount after purchasing my first flight, backpack, camera and a few bits and pieces. I have 3 months til I leave (nearly) and have a basic plan but am not sure about the 'real world' out there, and how much things will really cost etc.
Leaving Aus --> Japan for about 12 days (With a friend - Osaka with daytrips to Kyoto + Nara, Hiroshima, Nagasaki and Tokyo)
Tokyo --> Seoul (to visit a friend for about 11 days)
Seoul --> London (maybe 3 days - just a stopover though mainly)
London --> Stockholm (meeting a friend for a week, we are then traveling together for maybe 2 more weeks)
Denmark (Roskilde Festival + Copenhagen, staying with a friend the whole time.)
Berlin ? --> Budapest (4 days here)
Before going to France by myself to visit some of the following: Strasbourg, Nancy, Lyon, Marseille, Toulouse + Carcassone, Bordeaux, Paris (About 16 days in France)
Paris --> Geneva (for maybe 3 days) before getting a flight back to Stockholm about the 3rd of August.
The staying in Stockholm on a Working Holiday Visa for however long (if I don't find work, then a very short amount of time!) then travel more til I run out of money and then come home!
Any advice would be amazing on budgets or must-sees etc.
