I posted this earlier in the thread, but here it is again. I'm a D23 member so I received the invitation to try
Genie+ for free on 10/19. Here is the wording from the fine print. It specifically mentions only being allowed one Genie+ LL pass per ride - I highlighted it in bold:
*Attractions with Lightning Lane entrances that are Disney Genie+ and individual purchases are limited in availability, subject to change or closure, may vary by date, and are not guaranteed.
To enter a theme park, both a valid admission and theme park reservation for the same park and same date are required.
Park reservations are limited, subject to availability, and are not guaranteed for any specific dates or park. Price, terms and entitlements are subject to restrictions, and change or cancellation without notice.
