Thanks for all the responses!
I was disappointed to hear that the VW bus won't be allowed on this trip, but glad that normal conveniences won't pose a problem!
In terms of the weather... thanks for the good advice. We'll make sure to bring plenty of warm clothing and weather gear. Lately it seems like all of our trips have been in the rain and cold... Is it too much to hope that we might actually see the sun on this trip?
Anyway, I've been doing my homework, but would appreciate any other words of wisdom you might have.
