There is conflicting information. So far, everyone seems to agree that ADR's open on Monday, 8/20. However, ADR's are only available through the phone on that date. On 8/22, online ADR's will become available.
The conflicting part is that on 8/20, ADR's are going to be available at Noon, where others are saying 7am. So, I am going to be on the phone on Monday at 6:55am just incase.
Its not surprising since CM's have been given the wrong information before and are all not in sync with eachother...
The only other part I'm trying to figure out is the date they will allow ADR's. If it starts on Dec. 6th, then the preview period starting in Nov will only be walk ups and tables will be impossible to come by.
