Yes and no. For most ships tours you meet in one of the lounges at at preset time and are escorted off the ship by either the tour guide or a Carnival rep. If your tour is later in the day you normally meet the tour guide on the pier so getting off first does not apply. The ones that meet in the lounges leave at staggered times although several tours might leave at the same time so you may get off first or not. If not first off and there is a line to get off you will be escorted past those waiting in line not on a ships tour.
