Just wanted to also add my experience without getting an email. There appears to be a lot of glitches in their computer system. I had booked Paradise Pier last fall for 5/30-6/1. Not only have I not gotten an email, when I went to the website just to look at my reservation, I couldn't even find it. It was asking for an 8 digit conf number and mine was 12. I called the hotel and apparently they changed the booking systems some time and they gave me my new conf number. They also transferred me to the Star Wars hotline (no wait at all) and the lady found my reservation and told me 8-12 AM on opening day is my assigned time. She said there was no email listed on my account (even though of course I had put one and gotten my initial confirmation email).
So I guess the point is, if you haven't gotten an email, and especially if you made a reservation for the hotel several months ago, you probably need to call.
