Well, I feel much better now. We got a room in the hotel by about 11:30 am and went to sleep (we had had to wait a few hours until check-out, so we went to a cafe around the corner); and I got up at about 7 pm. We went across the street and had Indian food for dinner. The Chicken Tikka Masala was amazing! Tomorrow we are going to Speaker's Corner in Hyde Park. It should be interesting.
