I hope so. I would assume there will extra CM's available at 7:01 AM EST - or the best rated CM's they have on 10/27/09.
The website may crash with so many hits - or you may think you have the ADR - to find out later the website crashed and your ADR was erased.
The way a database works - 'entires' are entered into the correct 'slot - by a key, such as Guest name, phone #, reservation #, park, restaurant, & time. Entries can be made during a time period as in 6 AM to midnight (day 1). Then at midnight the full database is updated and a backup file (full copy) of the database is created. The ADR database would then be brought back up at 6 AM EST (day 2).
If the ADR database crashes on day 2 (lets say 10/27/09) - when the database is 'fixed' and is available it will come up with the lastest ADR backup file created on day1.
(I was a systems programmer for 21 years before resizing)
We are in the same boat - calling on 10/27/09 for our Easter week ADR's.
I think calling will be more secure - by talking to a CM, they may have an old fashioned way of doing a backup, paper and pencil.
I wish everyone some pixie dust

and may everyone's magic ADR dreams come true
