I saw one review of the second EMM day where a poster had breakfast at Be Our Guest. They said they were held until around 8:45 then released to the standby line at 7 dwarfs (no idea whether they could have headed to other rides). They beat the regular rope drop folks and EMM people were still going through the fastpass line. I think they said they rode once quickly, then got in line again with about 20 min wait before the line had reached its usual proportions.
