Thanks very much, moondog and rkkwan! I wasn't sure how far through the week the holidays extend in practice. I was concerned people may still take the whole week and that trying to travel that weekend would be busy.
We're still debating between flying and taking the train. The train sounds like fun, but, of course, we won't see much overnight, and it will save time (and money, actually) to fly. But at least I can be fairly comfortable with either option. Thanks!
