Thanks!! We're in Phoenix and the allergens here haven't caused problems for her yet... but I'm still waiting for her to develop reactions to something. On the east coast, she had issues with grass more than anything, which we just don't have much of in our area (in a desert preserve, so no golf courses or the like). It wouldn't have occurred to me to check the weather, so I definitely appreciate the insight! I was more worried about the smoke, b/c it's so pervasive. We once stayed in a Chicago area hotel that was said to be completely non-smoking , and I walked into the room and said uh, what?? It reeked. "Well, it used to be a mix of smoking and non-smoking here, but it's been cleaned." Yeah, not enough. I had to smell-test rooms until we got to one that had always been non-smoking LOL! As far as I can tell, the Delano part of Mandalay has been non-smoking since it was built.
