I have asked a similar question regarding my budget for the UK, but i have one on Europe.
I am actually doing a Top Deck tour of Europe for 24 days and then spending time with my friends over there for another 15 days... if i budget for about 70Euros per day while on tour and 100 euros per day while with my friends would that be enough?? I will have money there as a back up, but am hoping i am on the right track :)
