I think it'll go like this:
June 3 is the first day CMs are currently blocked out of MK. So either:
(1) only MK CMs who work there will be able to do previews; or
(2) CM previews will start before June 3; or
(3) CM blockouts will change dates (and that in itself will be a hint).
If CM...
It's not total park capacity. I don't think anyone's saying that. At the headliner attractions, DAS use can be 50-75% of the entire Lightning Lane line. A decent rule of thumb is newer rides = higher DAS use.
2010 is when the article was written, yeah. So that was in the days with FastPass but before FP+. If you want to say all the stuff they've done since then adds 1 more attraction to that, I wouldn't argue.
Just over 150, from what I understand, in three groups of roughly equal size of 50 CMs:
The core group of full-time guides
A second team of past/semi-retired/part-time guides
A third group who could lead tours if needed
Disney said - on the record to the NYT - 10 attractions in the MK in December 2010.
Ten per day in the MK feels like a decent estimate. It’s not 15 or 5.
