On the first day in London we arrived at the hotel around 9:00 in the morning, and pretty much just walked around looking at the architecture and the local sights most of the day. We had to visit Harrods departments store to purchase something from Harrods for a grand child.
For me, the Tower of London was the most important sight to see in London. We decided to make our visit the first thing the next day. We had coffee first thing in the morning at an outdoor cafe and then walked over to the bus stop to catch the first bus to the Tower.
It turned out to be a great time to visit; we were almost the first people to arrive with hardly anyone else there.
To see the crown jewels, there is a moving walkway that you stand on and it takes you around the crown jewel display. At the crown jewels area they don't however, let you take any photos even without a flash.

One of many narrow staircases found throughout the Tower.
Photo is a little out of focus... but still... that poor horse.
