Walking from County Hall to :
St. Paul's Cathedral,
Tower of London,
Ceremony of the Keys
We have about 7 hours from when we leave County Hall to when we arrive for the Ceremony of the Keys. We are in good walking condition; but, are open to all suggestions of recommended transportation
What is the recommended way to leave Ceremony of the Keys back to County Hall.
Again, thank you to everyone with their great posts and suggestions. They are much appreciated.
