Rather than return the car to Paris, we decided to keep the car for another two weeks and cross the English Channel on a ferry. The limitation of carrying two bags per person on the Chunnel influenced the decision. We opted for a 5-person cabin on the ferry. The kids felt they were at the Ritz. It was a cut above the ferry from Bari to Patras. Our ship was the Stena Hollandica.
Rather than drive to London and arrive in the evening, we stayed in the port city of Harwich. Our car GPS lead us to the correct address but we did not see the sign for The Good Life Guest House.
