Seemed good value at time and I hadn't cruised with Norwegian before. No queues etc at gatwick - brill! Smooth on time flight - brill! arrived Barcelona immigration arrivals - packed to bursting point with thousands of passengers - some from the USA - and no perceivable queue movement. Hot, stuffy, no toilets or water. After realisation that more staff an better organisation required some more immigration staff arrived and queue started to move. After about 3 hours we were on a coach to the port. Shock horror when we arrived at the quayside - a seemingly endless queue of people carrying their luggage. Length of queue at least twice the length of ship which is about a kilometre long. Total chaos, no management present except once when I pleaded with a Dep. Catering Manager to distribute water as I was concerned that people, especially the frail, would faint/collapse in such intense sun and heat with no shade. Needles to say we were still without toilet facilities. we eventually entered a portside building where Covid Docs were examined. Total queuing time at least 6 hours. When I confronted the General Manager of the ship he told me that the management were aware of the situation but were no responsible for passengers until they were on board. Please form your own conclusions including the fact that no apologies were given. NEVER AGAIN!!
