Time to Debark at an In-Transit Port (Barcelona)

[Luvsparties]

We are boarding the Preziosa at Barcelona, which is an in-transit (I think that's what it is called) stop. Upon our return, the ship is supposed to dock at noon. If I carry my own bags off, is it safe to assume I'd be off by 1:00 p.m. (1300)? I really want to get the soonest flight I can. I'm assuming they get all departing passengers off before the new ones are let on?

 

Thanks!
