Spain and Portugal - mid June - Essentials / wish I'd brought...?

... 2 pin adapter...

Yes, good to remember that. As it's a French ship you'll need a continental to UK adapter if you want to charge your phone, tablet, etc. on board.

Not sure where you plan to go but you might get some ideas from this account of our trip last year.

If you have calm weather there are great opportunities for whale and dolphin watching, especially when you reach the Bay of Biscay. Binoculars will be helpful.

On the way back to UK on the Cap Finistère in January we watched for ages the porpoises playing in the ship's wake. A lovely sight.

If you are going to dine in the restaurant (Restaurant du Port), I can recommend the tournedos, as long as you like beef and like it rare/medium and as long as it's on the menu, of course!

I am not generally a big red meat eater, but I always make an exception on the Cap Finistère when tournedos is on the menu.
