As usual (it seems with Carnival)...it answer is....
On the Liberty in November and the Destiny in December....we got the VIP letter and we were able to put our luggage out and still be the very first ones off this ship. This is a NEW method. (which I LOVE!!!!) No more having to haul all my luggage off the ship myself.
We just got off the Elation today and they still use the old method where IF you want to be the first off the ship....you have to carry your luggage off.
VIP self assist got off the ship at 7AM (DJ was the first person off...he loved that).
VIP "regular" (putting your luggage out) were not instructed to meet until 8AM ... which means they get behind all the self assist...which is not much of a benefit.
It truly depends on how YOUR ship is doing it.
