Guys -- book your hotels for DEMA now. The Rosen Centre has already booked full at the DEMA site. We stayed there last year, and it was nice.
(I went to the site a couple days ago and there was still availability! But then, I had to ask the WP staff whether they wanted to go, and that two day delay was enough to make me miss it. grrrr...).
You can still get rooms for $249 ea. through the Rosen Center website itself.
I booked just now at the Days Inn Convention Center, which is also very close. It's cheaper, but I'd probably have paid the extra $50/night for the comfort of the Rosen Centre. Oh well.
