I just got off the Sapphire princess -- I asked about this at the guest services desk, and was told it was not allowed-- that "express" meant that you had your credit card on file. Since there was an escalator, I really don't see how anyone could manage, unless all they had was carry-on luggage. Considering how slow the elevators were, and how quickly one could claim their baggage, I don't see the benefit. If anyone wanted to speed up their disembarkation, the passport line moved very quickly! The wait was in these lines, not in baggage claim. They called disembarkation by tag colors, so even if you had all your luggage, they checked for the claim stub before they let you off.
