So much history there. In case we do eventually visit, what is on your “must-see” list?
Trafalgar and Piccadilly Squares. The Mall. Houses of Parliament and Buckingham Palace. Westminster Abbey. St. Paul’s Cathedral. Ride on the top of a double-decker bus and in the Tube (if there is not terrorist alert). Take a guided tour around the city. Eat in one of London’s Indian restaurants, have an English breakfast, and visit a Pub and drink warm local ale.
Consult a guidebook, and get help from your hotel. And get help from the State Department re any terrorist alerts.
I doubt if anything will be as good (or as safe) as it was before the hordes of muslims arrived. I did not see a single hi|jab when I was there (to attend a conference-—not as a tourist).
