Embarking the Seaview at Barcelona

Hi again... Can anyone suggest the best time to embark on the Seaview from Barcelona for Bella balcony passengers (I mean when is there the less queue usually and when will MSC let us board)? The ship will depart at 6pm. Thank you

Hi. MSC will begin boarding approx 2 hrs after docking. I think it tends to be busiest from 12.00 til 2.00pm. I would turn up either by 11.00 or after 3pm for quieter times. You need to be onboard at least 90 mins before departure time. Ken

Thank you very much for your kind help
