Free international travel.

After traveling 4 countries, I believe traveling AROUND AND ACROSS the globe has got to be the most enriching, enlightening and educating moment of everyone's life. It's because you get to interact with the locals, you witness moments that you couldn't find in your own country and how being in a new country with a whole new culture to take in, you learn things.

One free trip to space is of course a truly once a life time opportunity but I would rather go for an international travel for life. Because, there's so much more out there for you to explore and discover, why restrict to the galaxy when you could have the world?
