Thanks for the info on airports, carpooling, earplugs, etc., folks.   Sounds like I'm really gonna be able to make it this year.   

BTW, how important is it to bring our axes with us?   I don't like to take my old Martin with me on planes, especially when it's not a non-stop flight and I can't take her on board with me. But I have trouble playing anything that doesn't have a narrow neck and light-gauge strings. Are there usually a lot of different guitar types that people will let others use occasionally in a jam, sing-around, or the concert?   

I may bring my itty bitty Ibanez, since I can take it on board. Doesn't make a lot of noise, but it's very portable.   Or maybe I'll just bring the Sigma. The action and sound aren't as good as the real Martin, but it would be much less a heartbreak if it got lost, stolen, or broken.
What do you other 'foreigners' do?
