Referring back to my original list of questions, here's what I think we know right now. This is based on my reading of this group and other sources. Let me know if I got something wrong, though.
> Will parties be open to secure boarding passes from either park, or only in
Disneyland?
It sounds like you will have to enter Disneyland in order to enter a boarding group. I assume that once you've scanned into the park you can probably get a boarding pass from anywhere, but that remains to be proven.
> Will it be possible to secure multiple boarding passes per day?
Unknown. At least initially I suspect that it will be difficult to secure a boarding pass any time beyond the initial rush, so this will probably remain unanswered until things calm down.
> Will it be necessary to get a new version of the Disneyland app?
It doesn't seem like it. Disney hasn't released a new version.
> What is the procedure for guests who don't have cell phones?
Disney cast members will apparently serve up boarding group numbers from the old Buzz Lightyear / Star Tours Fast Pass area. It isn't clear whether they are available from other sites as well.
> What is the typical highest boarding group number issued, and when do boarding passes run out?
Unknown. The DHS version seems to typically get up into the high hundreds, but it varies from day to day.
> Does everyone in my party have to scan into the park in order to join a boarding group?
Yes. No one in the party will receive a boarding pass if even a single member hasn't entered the park. You'll need to remove absent members from your party in order to join.
