Spanish Crossings:
I have only used BDS for crossings to Spain. When we have, we book a commodore cabin and lock ourselves away for the voyage.
I love the very expensive Balcony cabins on PA, but overall, apart from the queueing for the Restaurant bookings, CF is our overall favourite. I have chosen to avoid Etretat.
But Why is Santander the more popular choice of port?.
Bilbao for us.
