Came back here to update:
I happen to agree with all of you, and felt making a change was wholly unnecessary, but the faction that wanted to switch gained enough traction that more people decided it was unsafe to go to Mexico.
We didn't have the budget to switch to Bahamas due to the flight, plus it would entail going into the next work week (which was a no-go for several parents), so a compromise was made to switch to a Baja cruise going to Catalina Island instead.
It would still allow us to drive, making the "we don't want to fly" crowd happy. It still occurs within the same week, making the crowd that can't take that next Monday off from work happy. And it has a port call in the US (Catalina) making the "we won't get off the ship in Mexico" crowd happy.
It's certainly not the ideal compromise, since it still goes to Ensenada regardless, and now we lose Cabo. But I just didn't want to deal with it anymore. Whatever.
I'm calling travel agent tomorrow. I am so tired. Cookie season just ended, and everything comes due at the same time. (I am a law professor, and have a ton of exams to grade tomorrow) Final payment date is March 16, so I guess we'll just go ahead and pay the balance when I make our change.
