My gf spoke to Madison House today. She's been very worried that she screwed up the booking process, but they said she had not. They went on to say they'd be calling everyone individually during the next few days to, basically, discuss their order.
I dealt with Madison House a few years ago when they hooked me up with a real nice hotel/ticket package for a SCI show in Columbus, OH. My experience with them was amazing and I still remember the name of the supernice agent I spoke with, Shelly

So as long as you got a conf number, I wouldn't worry.
...sick laser light display at that SCI show by the way, wonder why I haven't seen them use lasers since...
