Good luck to all of you still trying, just wanted to give an update on what happened for me. Was in queue right at 7:00:20 EST, waited 90 minutes to get a CM. When I spoke with her, she said they were having system issues that the discounts weren't set up correct in the pc's for all of the rooms/discounts, and that right at 7 am there were 1,100 people in queue. Not sure where she was getting her info, but sounded legitimate as she had talked to their tech support about the reservations before me, and they told her about the discount issue and weren't able to resolve for them (BOO, very sorry for them

).
I ended up spending the next hour on the phone with the fabulous CM, who despite all of the issues, seemed very happy to make our first visit to the mouse as magical as could be

! This CM went above and beyond to make sure our every need and wish was met and that I took care of everything I needed to while on the phone! I started out

due to the wait time (BAD IT department

), but ended up overjoyed! Let the countdown begin!
Anyhow hang in there, it seems the website was allowing the codes through, but I couldn't do a multi-room booking. My advise if you don't have to modify an existing reservation would be to use the web, and sign in with two accounts if you need a multiple room booking!
Best wishes to all! I am so excited as this will be our entire party's first trip to Disney World, our twins 5th birthday celebration (we come home the day before their birthday), and DW and my 10 yr wedding anniversary!
