Brazil
Some people are going to groan at the name, but bear with it. If you are young at heart and looking for a variety of fun things to do in Rio, you could do worse than pick up the "Rio for Partiers" guide. It's a little bit like this site - crammed full of tips, and just the thing to turn to if you are wondering "what to do next" in Rio.
It's not the "club 18-30"-ish guide that it seems from the title. I'd recommend at least having a look at it in a bookshop - many of the places in it were things which Cariocas recommended to me anyway.
