Posting this again. A lot of questions being asked again are answered here:
Summary of what I learned today!
Buying genie +
You can purchase
genie+ in two ways. You can buy it the day off after midnight or you can add it to your vacation package ticket. If you add it to your package you have to commit to it for every day you have a ticket.
120 minute rule
The 120 minute rule comes into play 2 different ways. The first way is if you book a genie+ at 7am for more than 2 hours after park opening you can make another selection 2 hours after the park opens.
The second way is once the park is open. Once the park has been open and you make a selection that is more than 2 hours away you can make another one in 2 hours.
7am rule for off site
If you are staying off site you can make Genie+ reservations at 7am BUT YOU CANNOT MAKE INDIVIDUAL LIGHTNING LANE SELECTIONS UNTIL PARK
OPENING. Park opening of the park you are buying for. If you are buying Remy and are off site, you can buy Remy when Epcot opens.
7am rule for on site
If you are staying on site you can make BOTH an individual lightning lane selection and genie+ selection at 7am.
Refreshing
You can refresh the my tips page to try and get earlier or different times offered to you. However you CANNOT cancel or modify an individual lightning lane pass.
You can cancel a genie+ pass and book another one. You cannot modify an existing one.
Park hopping
The app recognizes your park hopper. You can book genie+ selections in other parks after 2pm. You can also make Individual lightning lane selections for other parks at 7am(onsite) or park opening (offsite).
Choosing a time
For genie+ you have to pick the time the app gives you.
For individual lightning lane the app will show a time BUT you can click on it and then will be able to choose from all available times.
You can buy both lightning lane selections at the same time.
Stacking
Stacking is confirmed possible and you can hold multiple Genie+ selections at a time. You can also hold virtual que, individual lightening lane and genie+ selections all at the same time.
Virtual que
Right now Remy is the only ride with the virtual que and the drop is at 7 and 1pm. You can use this along with individual lightning lane and genie+. You can use virtual que and individual lightning lane for the same ride.
Patterns from day 1
Hollywood studios saw rides run out of passes. Rise ran out of individual lightning lanes by 945 and slinky dog and smugglers ran out of genie+ early afternoon.
Magic kingdom saw jungle cruise run out of genie+. Individual lightning lane passes for SDMT and space have not run out. Most return times are right away/ next hour at this moment.
Epcot nothing had run out and return times are right away/next hour.
AK nothing had run out and return times are right away/next hour.
What happens if the ride is down
It seems when a ride is down a ride anytime pass is issued.
