My husband and I sailed on Carnival Liberty from May 6th to the 12th 2007. A little background on us - we are in our late thirties and are very well travelled - we generally take at least 3-5 vacations a year and that doesn't include last minute weekend getaways to Cape Cod, New Hampshire, Maine, Connecticut, New York, etc. that we can drive to. This was our first time on Carnival. We usually sail on Royal Caribbean and Norwegian when we cruise.
Embarkation: We arrived at the airport (flew Jet Blue) about 30-40 mins earlier than scheduled. We met our friends (Tate & Shana) and shared a cab to the ship terminal.
Once at the terminal, we waited in line about 40+/- minutes to board...not bad considering I've waited in line for 1-2 hours before at other terminals. Once inside, the line moved quickly. We got up to the desk and then was told...here is your sail and sign card but now you must go up to the lounge (I think it was deck 5) and activate your account up there. This was rather annoying that they wouldn't process it right then and there like my friend (Adam) told me they did for him about an hour earlier when he arrived. So, off we went and stood in another line for 20 mins to activate our card.
