I'm also looking to get away in Dec. I'm looking for travel to occur between Dec 6 and 19. I'm sure we could find a 4 or 5 nighter that fits in that. I'm looking at sailings from FL.
I've also cruise a bit with Carnival... get small discount. I'm on a budget and spend little time in cabin, so I prefer smaller rooms for booking and take the upgrade when offered.
I'm 39, DWM, glad to share lots of info, phone or chat online.
Drop me a reply; I'll PM you also with my email.
