I booked a ticket on the Eurostar for my trip in the fall. I don't normally book train tickets before I go because I want to be flexible, but the Eurostar fills up and I do want to take a specific train. They run every hour, I am taking one that leaves Paris around 11 and arrives in London around 1. There is an hour time difference so we'll be on the train ~2 1/2 hours. I figure leaving at 11 gives us enough time for breakfast and to say goodbye, and arriving at 1 in London will give us time to check into the new BnB and visit the local area of Kingstone. Tickets cost ~$70 US. We don't have reserved seats.
