China, followed closely by all of the Greek islands I've visited since I adore Greece and it's culture and it's talent .

Buenos Aires, Santiago, Lisbon/Sintra and Paris.

Ontario, Canada (esp. London)
Port Douglas, Australia (and great barrier reef)

and then Dorset (swanage and bournemouth)

I've never been out of the US

My favorite places I've visited are San Francisco, Salt Lake City, and Las Vegas though

Seriously? I live like an hour away from London, my mom absolutely loathes that city since the traffic is soooo bad. I've been there a couple times for shopping and a couple shows. It's very clean but confusing to navigate through
