London is wonderful, amazing, and I'm sure you will have a great time. For getting your body moved around, the Underground or "Tube" is can't be beat. Check into the offerings for "all you can ride". It's been a while since I've been there, so don't have current details, but some people swear by an "Oyster Card". The beauty of any of the "all you can ride" deals is you don't have to fumble with unfamiliar change and queue up to buy tickets all the time. And when you inevitably take some train in the wrong direction, you just step off and get on the right one without buying yet another ticket. "Pub grub" is fun and good, people tend to walk on the sidewalks as they drive (the opposite side from the US), the British Museum is FREE!, bus tours on those double deckers are an effective/inexpensive way to cover a lot of ground, I highly recommend an armload of guide books from your local library, and I really highly recommend the Lonely Planet London guide book for taking with you (great maps and directions and details). Oh yes, pick your lunch places by choosing the ones with the longest line. Romelle
