Has anyone used the Portsmouth to Bilbao/Santander Brittany Ferries Economie service. The ordinary sailings on the bigger boats to Bilbao for September are all full. All the over winterer's going over! I can go Santander but prefer Bilbao - Haro - Benicassim. The general facilities look much less but perfectly adequate and the boat smaller. Cabins look ok. Maybe a bit rougher if conditions are bad. Looking for a Funster who has had first-hand experience using the Economies service. Thank you in anticipation!
