Going to Rio alone (Rio de Janeiro)

Hi there, I've just booked my flight to Rio for April. You have no idea how excited I am! Or maybe you have? lol

Anyways, I am going alone and I thought maybe there's someone who wouldn't mind sharing a coffee with me, or a beer or a walk down Ipanema beach one day?

Also, any tips, suggestions and feedback is greatly appreciated.

Thanks and (hopefully) talk to you soon :)
