Arrived in Barcelona a day early. Stayed at the Hispanos Suiza, which was a 2-bedroom hotel (apartment) with a small kitchen. It was great for the four of us (2 adults & 2 kids). We could hear the people upstairs and outside the hall all night...I think they were preparing for a wedding.
Took a cab to the port. I don't remember how much it was. NCL check-in was very quick and easy.
No tenders, the shipped docked at all of the ports.
