I think Jim and I have decided on a 11 day cruise on the fairly-new Celebrity Equinox sailing 2/7 - 2/18. Here's a map of the itinerary:
We have not been to Cartagena, Colon, or Puerto Limon before, so there will be three new countries to add to our list; Colombia, Panama and Costa Rica. We've been to Cozumel, Costa Maya and Grand Cayman before, but we like all of those ports, especially Grand Cayman, and will find new things to explore there. A big plus is that it is round trip Fort Lauderdale, which is a short, cheap flight for us and one that we can still get relatively cheaply even though this is only a month out. We haven't been on a cruise since South America in 2008 so we are READY!
