Hi Unky! :)
I'm sure I'll be fine. It's just getting there (long flight and finding the way to my hotel) that make me a little nervous. I speak a little Spanish, but emphasize "little". I'm confident the work will go well, and my husband is coming to visit for a week in the middle of my assignment. I'm really looking forward to that.
Bear - I hope you are just joking. Nothing is worth that much stress.
