Glad to hear you've cruised on the Spirit several times before. You must like it. I've never cruised on Carnival before and I was reluctant to book with them because they are the most mass market of all the mass market cruiselines. It must not be too bad if you've gone on repeat cruises on that ship. The low low single occupancy fare is what got me.
Tell me about the FOD meetings.
When was the last time you cruised on the Spirit? Maybe the same Cruise Director is still aboard. If the CD is the same, maybe the FOD experience will be the same that you've had.
