We ended up going to the British Museum for our dose of culture and history :) I am not sure why but Caitlin was keen to go to the National Gallery and see some art. Perhaps next time we are in London I will take her to see it and the V&A as I don't think the boys were particularly keen :)
There was lots to see in the museum and it kept us all entertained for the better part of the day. It was then back to our hotel so I could finish packing while Ken took the kids and himself for one last swim in the hotel's pool.
Then I think it will be a light meal in our room and then an early night for all of us. Our flight to New York isn't too early but we still have to be up at the crack of dawn to get ourselves to Paddington train station to catch the Heathrow Express to the airport in plenty of time.
