Why do you want others to bankroll your vacation? You know you'll end up sleeping like a hobo and doing manual labor for food. Why the bitcoin pretense?
I didn't say anything about getting others to bankroll or donate.
although it would be nice, It is doubtful I'll get any substantial amount per day.
Support can be given in many ways. Notice I mentioned Buddy Passes for Bitcoins. Tickets will be quite expensive, and almost impossible to buy with BTC, but I'm sure someone out there works for an Airline and could get me some buddy passes in exchange for BTC. I might be able to convince a friend in the airline industry to get me a buddy pass for bitcoins.
I know people that work for the following airlines, Delta/Northwest, US, United, Continental. Last time I needed a buddy pass it was $150 to anywhere in the US. I don't remember how much for international. One Airline friend to International trips regularly with Flight Benefits. I don't know about the Cruise Line industry, I've only known one person that has worked on one. However Getting My friends to even look at BTC has been difficult.
However on second thought why wouldn't someone want a Community to Bankroll a Vacation for them.
