Don't miss a tour of Hampton Court Palace and its gardens. A convenient train ride down there, and you can go all the way down or back on a boat on the Thames. You have to see the usual things in London--Parliament, Big Ben, St. Paul's, Trafalgar Square, the National Gallery, and of course the wonderful, terrible Tower of London! Just wandering the streets of London (mostly the West End) is an endless fascination, but be very wary, as the bad guys are out in force and it's pretty dangerous now. Take a day to run up to Oxford by train. Bath is gorgeous and very ancient. If you have time and money, drive through the Cotswolds where you can OD on the sheer historicity and charm. Travelling by car is staggeringly expensive as gas is about $7 a gallon. Yes, you read that right. Have fun!
$7 a gallon! YIKES! We won't be driving and I am glad- I am totally afraid of driving on the wrong side of the road! LOL! All of these things sound wonderful!
