Most of the time to get the discounted ROOM you have to be there first and
they always have a way of refusing. I would not want to arrive there
without a room.
$99 at a nice Disney Hotel is a pretty good price. I used to go to Disney alot but rarely had to pay. My sister worked as Dale (from Chip and Dale) and
a couple other characters. She was also Betty Boop on a Forth of July
Special on TV.
With Travel down a bit rooms have went up over the last couple years.
Heres a link that might help.

Also do a couple searches for Disney tips and you will find some great
and $$$$ saving tips if planning on attending the sights along with the
pool event. Theres a disney newsletter put out by a fan thats very good
as well. A search should find it.
