Hi Bob, as it happens I'm booked on Navigator out of New Orleans on January 26 just before Mardi Gras. I've never cruised out of New Orleans before but I do have 260 cruise nights on Royal Caribbean and wouldn't go with anyone else. I know that Celebrity is billed as the Royal's upscale line but I actually like Royal Caribbean better. I've been on most of their ships and on Navigator about 6 or 7 times. I think you'll love the ship and the crew.
Any thoughts of backing up your trip to January? I've got about a dozen in my group right now and we actually chose our date so that we could catch some Mardi Gras parades before the cruise.
