I can tell you that the AP previews worked to fill up a hotel room. Trying to stay first weekend of previews, all values were booked and a few moderates were left. A lot of "Standard" deluxe rooms also booked. Now, we know Disney plays funny business with room availability sometimes. But still. That's something. I do think early on Avatar will draw in the out of state APs. And will probably draw in some additional holiday and summer traffic. But I wonder what will happen when school goes back in and less US families are able to travel.
