I was there during the soft-open period and got group 11, and we got called at 8:46 with a "by time" of 9:46. Our situation was a little funny so I spoke with three cast members to try to figure out the best solution (which ultimately we ended up winging it). I found out that there is an unofficial but very firm 1-hour extension of your "by time," which presumably accounts for the potentially lengthy build up of people in the VQ (we waited ~an hour before even tapping in), and users with
DAS can request a return time in accordance with their VQ boarding group that extends their "by time" by one hour. I didn't use that feature, so I'm not sure how it actually works. I posted my experience in the VQ thread, and I would hope that others post updates there now that the ride is officially open.
