WOW, thanks for all of the ideas.
Jamo, I stay in Holiday Inns on business on a regular basis so I have a ton of points which I wanted to use. I ended up reserving a room in the London Park Lane, One Hamilton Place. It is between Hyde Park and the Buckingham Palace grounds. From what I hear, it is a classy "joint". From what I can see on the map, it is close to a "Tube" station and it isn't too far from the tourist area.
I have been told that the best way to get around London is using the Tube. We are flying into Heathrow and I believe that we can get a week's pass right at the airport and then take the Tube into London. I will certainly also try the double decker buses and of course at least one London Cab.
I plan on trying to visit as many of the spots that have been mentioned as I can in one week. I will also try to visit as many pubs as possible and try many different brands of beer. A friend has told me that Churchill's war bunker is a must see.
One concern was understanding the currency but I have been told that the Pound now contains 100 pennies and is broken down more or less the same way as out dollar. This should make using cash much easier.
Lineslinger, will do.

I am really looking forward to this trip.
Thanks again for the ideas and suggestions.
