We stayed with friends in London ---big thanks to Caitlin and Billy!--- and I felt like I had my own personal tour guides. In between her work, Caitlin graciously showed us the sights and on her work days she helped me plan our train/underground routes for the day.
Grace's highlights of London were...
---the street performers on the South Bank
---the London Zoo
---taking trains everywhere and anywhere
After the first day, she started calling money "pounds" automatically (to my great surprise!).
I loved St Paul's Cathedral and the houses of Parliment.
Everyone in London was so kind to us and Grace won everyone over, everywhere we went. I mastered carrying a toddler, stroller, a 40lb backpack and a 15lb shoulder bag through the London underground while digging out my ticket to get through the gate...only to find that it was three flights of stairs down, with no 'lift'. Plenty of very kind Londoners carried our stuff up and down stairs for us almost everyday. Someone always offered to help.
