We were booked on the evening crossing to Santander, scheduled to arrive at 17:30 on the Saturday. We had been in touch with Camping de Haro in Haro, Spain which is around a 2 hour drive (190km) from the port of Santander and would just take the edge of a very long drive the next day.
The campsite had indicated space wouldn’t be a problem but reception closes at 18:00; however security would be happy to site us after that. Arriving after 22:00 was considered by them less than ideal.
Our dilemma on reaching Portsmouth was that due to bad weather in the Bay of Biscay the prior weekend, the schedule was recovering and still 2 hours behind our arrival time of 17:30, leaving just 30 minutes to offload and then precisely 2 hours to reach Haro, some of the drive being in the dark in a country we had never towed in before.
This weekend the Bay of Biscay was kind and we had a pleasant smooth crossing. I hope for similar on the return journey.
