How do you share a PhotoPass Acct?

I am interested in learning how to share a Photo Pass account to reduce the cost.

It sounds like the process is:
1/ create a MDE account (separate from where each person has their reservations, FPP, itinerary, etc.) that all the parties will share using the same password
2/ purchase a a Photo Pass under it and link up the magic bands
3/ After/during your visit, everybody who shares in the cost goes to that account to view/download photos & videos

Is this right? Is there a limit to how many magic bands can be linked to one Photo Pass? Can anybody confirm it works?

These are the instructions I found on line
