Barcelona Port of Call question, disembarkation.

[marc_b2001]

Hello all, we have a scheduled arrival in Barcelona at 9:00am and was woundering what time we actually get off the ship? Are they sometimes ahead of schedule or pretty much "on time" (my past cruises with Carnival were a mix of early and on time arrivals). And how long does it take to get off ship, any customs or security to go through?

Thanks
