Cleaning commonly-touched room surfaces with Lysol/etc. is very smart! I hadn't thought of that but I'll be doing that for sure. I don't know; hopefully it will be nice and chilly and I'll wear gloves to help keep me from touching stuff in the parks.

I do have the "luxury"

of not having to fly so I don't have to worry about that aspect, at least.
I wouldn't forget the importance of keeping warm and not wearing yourself down; I think that's almost as important as keeping your hands clean. In June we went and I was the only one in my party who used hand sanitizer consistently, yet I was also the only one to get sick. It very well might have just been a fluke, but I also went out at night without my jacket, figuring I'd be OK...it wasn't horribly cold (though I'm from Arizona, so yes,
I was cold!). But I think that being out alone in the cold night air MIGHT be what made me sick, or at least what kept my body from fighting it off as well as it could have. I think I only caught a little cold or something--I wasn't feeling very well the day after and not great the day after that when we went home, and was a touch under the weather for work the next day.
(I would like to get a vaccine so I would be less likely to get sick on vacation and to perhaps offer some protection in case H1N1 mutates, but I'm not in a high-risk group and we don't have many vaccines out here in the first place. If it doesn't become widely available here in the next couple weeks I likely won't go to any effort at all to get it, because it will be too late to protect me for my trip anyway. And I would not want to get vaccinated before everyone in a high-risk group who wanted it, got it.)
Anyway, I sure HOPE that H1N1 doesn't change my plans, because if it does, that would mean that either my friend or I was sick, or even worse, it's gotten significantly worse (as in, a lot closer to 1918 bad).
