You can get a round-trip flight to London for $500 or less, if you look around. I paid $550 for my flight. It was one of the greatest experiences of my life. Cities like Chicago, San Francisco, NYC, and DC are all cool places to visit, but there's nothing like being in another country to really shake it up. Besides, all of our cities *might* have something 200 years old, if they're lucky. I went to Paris and walked through Notre Dame, built by hand over 600 years ago. I went to church in Westminster Abbey, where monks were buried almost a thousand years ago. It's well worth the money. My wife and I spent two weeks in Europe (London and France), and our total came to $4000 (flights + lodging + channel tunnel train + subway passes in London and Paris + food + entertainment). If you were only paying for yourself, you could probably spend close to a week in London for about $1000. The public transportation is amazing, to say the least, and it was quite affordable, even though 1 pound = $2. It was $50 for unlimited subway/bus for a week. All the museums are free (so we went to seven different museums

). Greenwich was awesome, and so was Camden Town.
