Most people are lucky to be able to have one big trip like that in their lifetime. I couldn't imagine cashing it in on something that shitty. On top of that, I have to lose a ton of money and get accosted on the streets by all kinds of drunks and people selling you stuff? No thanks.
I'm lucky I live somewhere that has a lot of affordable vacation choices if you're into the outdoors. We can take a couple of smaller getaways every year because we do it on the cheap.
