Taxi fare from Barcelona down town to cruise terminal

In march we used three taxis to transport six of us plus luggage from the centre of Las Ramblas to the port. The cheapest was around 16 Euro and the dearest around 18 Euro for the same trip at the same time.

How much is a taxi from the cruise port in Barcelona to La Sagarda church

Last month (April 2016) we were staying at an apartment near the Sagrada. Taxi, four pieces of luggage, from BCN to the apartment was around 38 euros with tip. From the apartment to the cruise port, directly to the ship, was 20 with tip. I expect it will be a bit less to/from the Placa de Cat.
