I honestly don't need the $$$. But I just finished booking a Eurotrip from June 28th - July 22nd through Barcelona, Ibiza, zurich, munich, vienna, budapest, prague, berlin, amsterdam, and london. So now I kind of do need the money... For those curious, the trip is really not that expensive at all. Flights were like $1400 and the largest expense. After all travel/planes/trains and all hostels/hotels for all days, I've only spent $2300. I budgeted for 4k but it's looking like I get out with only 3K.
I suggest it! You'll never have 30 days to burn again in the rest of your life to do a backpacking euro trip. I'll be in $204,000 of debt instead of $200,000 of debt after medical school, so I don't think money should really stop us!
