Going to London in January, any ideas?

[Pastor Keith]

I am taking Jeanie, David to London, England on our way to India for our annual missions trip in January 2008, we will be there on a Saturday, Sunday and Monday, flying to India on Tuesday.

Any ideas of what to see, what to eat, recommendations on where to stay?
I am budgeting about 800-1000 for the 3 days we are there.
So we are on a budget, so I can't splurge.

On the list is the British Museum, Westminister Abbey, Imperial War Museum, Tower of London, taking a Walk tour, etc. Any others ideas, I have no idea what kinds of food we should try. So input from those that have been would be helpful.

Thanks in Advance
