Barcelona disposables

If you follow me on Instagram, you've probably already seen some of these. When I went to Barcelona a little while ago I brought two disposable cameras. I had forgotten how much fun it is too shoot with them! I'm going back to Barcelona in a few days and I was just wondering if you guys had some more tips for me. I've been there many times before and some of you have sent me some great tips already, but more is always welcome cause I'm gonna have quite a bit of alone time this time around.
