If you get a chance, read this book, it will enhance the trip. I was there about 15 years ago and had a great time. You guys will love it. I agree with GD, a trip out to stratford and stonehenge is well worth it. I enjoyed watching the bus driver navigate the roads in and out of London without hitting anyone, it's much more entertaining when you are in something big, and don't have to worry about it. One of my favorites was to go down to Greenwich and visit the prime meridian, and see Harrison's clocks, along with the National Maritime Museum.

Nobody ever takes my travel advice so I won't give it. Just make sure you leave a day or two to just randomly wander, take the subway, get off at a random stop, walk into a random bar or otherwise see real Londoners and not just other tourists and the Londoners who cater to tourists.

(Haven't been to London, but that is my truncated advice for traveling anywhere.)

Hit the London Dungeon. It's a short walk from the Tower, across Tower Bridge. It's like the Goth Disneyland.

No advice, since I've not been. Dying to go.

So, my words of wisdom, have a wonderful time! That's given. :D

We try to do a bit of this where ever we go, hit a market and make a picnic, stop and hang out at a park wit the locals, get recommendations from our waiters for places that would never be listed in a travel guide.

Check out the bookstores on Charing Cross Road. Bibliophile heaven.

My advice is to take me with you guys. :)

My favorite part of the LD is the plague room, which actually smells like plague!

Do the nerd thing and look for that Harry Potter platform (9 3/4) at King's Crossing. :)
I did...
:D

Next time I go over, the V&A is at the tippiest most top of my list.
