I do have a plan B if things get really crazy between now and then. All of our flights to/from CAI are refundable, and we could easily stay at our prior location for an extra day or two.

Overall, I think I still feel fine going based on the current situation, but I'm having a hard time describing what would be the cutoff point where I canceled everyhting. What do other's think? Military invovlement? Shutdown of the US Embassy?

Certainly if the tourist sights close, that defeats the entire purpose of going there, so I guess that's another cutoff point.
