Well, for my birthday my parents took me and my best friend to Rome, and it was amazing! I've always wanted to go to Italy, so if I had the opportunity, I would love to go back and maybe see some other places there.
I've been to Switzerland twice now, which was great, too. I love the whole atmosphere there, plus it's a really beautiful place, so of course I would love to go back there.
I think it'd be fun to go to Paris as well, because I only went there when I was 5 and we went to Disneyland. I think I'd probably appreciate it more now.
As for places I haven't been to before, I'd have to say Canada, Denmark and Iceland. I also really want to see the Northern and Southern Lights, but I don't know where to go for that.
