I'm keeping an eye on this because we're scheduled to fly down on the 23rd. We live in Montana, so this was our life all summer...the smoke in the air won't especially bother us (though it has been awful nice not to breathe smoke since the snow started a couple weeks ago), but we're concerned about the park closing due to fire danger. From what I'm reading, though, it sounds like that's not a concern at this time, though I'm seeing something about Orange County being in a state of emergency, which is not encouraging. My housemate made all the reservations (airline, airbnb, and rental car) so I'm poking her to check on all that (especially the airbnb). We haven't bought our park tickets yet, and now we're probably going to wait until next week to commit to it.
