Just a suggestion, at the risk of stating the obvious. I found that it helped to practice making an ADR beforehand, to familiarize myself with the site and the procedures. If you're staying onsite, put in your reservation number and other info, to be sure the sytem recognizes it. You can pull up your reservation before your 90 day window opens. Then pick a restaurant and fool around choosing dates just to see what the other screens look like. It helped me to be very efficient when it came time to make my ADR's - and at 3 AM, I didn't want to be wasting any time!
