To (hopefully) answer multiple questions, I
think this is how it will work (although there was some mention of potential tweaks before launch, so take it with a grain of salt until it's officially released). If you are on onsite guest, you can do the following at 7am: join Virtual Queues, make your first
Genie+ reservation, make an LL$ reservation. Offsite guests can join Virtual Queues at 7am, but they cannot make Genie+ or LL$ reservations until they physically enter a theme park.
Expanding: Genie+ and LL$ will be separate. You can take advantage of one, both, or neither. You can only make a maximum of two LL$ reservations per day. It's possible you will be able to make both LL$ reservations at the same time at 7am, but that wasn't entirely clear. There are no limits to the number of Genie+ reservations you can make each day. However, you will only be able to make one Genie+ reservation at a time. It's possible that you will ultimately be able to hold more than one Genie+ reservation if the system works like DL's MaxPass did (when making a MaxPass, a notification popped up that you would be able to make another one either after scanning in for your current MaxPass reservation or at "x time"...and sometimes "x time" was sooner than your current MaxPass reservation window). That part wasn't clear though.
So here's what I'm thinking a day at MK could
possibly look like for an onsite guest.
7am: Make Genie+ reservation for BTMR with a 9:30am-10:30am return window. Purchase LL$ for 7DMT with a 10:30am-11:30am window.
8:30am: Enter MK for Early Entry (assuming the park opens at 9am). Ride Space standby.
8:50am?: Ride PP standby.
9:00am: First offsite guests coming into the park and making first Genie+ reservation (onsite already has done 2 attractions).
9:15am-10:15am (this is generous ~ might not take this long): Off PP. Ride 1-2 attractions standby.
9:30am: Make second Genie+ reservation if new window has opened and stacking is allowed.
10:15am: Ride BTMR with Genie+.
10:30am: Ride second Genie+ attraction if stacking was allowed, then make another. If stacking isn't allowed, make second Genie+.
11:00am: Ride 7DMT with LL$.
11:15am: Spend the next few hours doing "Anytime Attractions" like PhilharMagic/Monsters Inc/HoP/CoP, lunch, working in Genie+ ressies.
That would mean on onsite guest could potentially do 7-8 popular attractions in less than 3 hours. It would free up the afternoon for pool time, Park Hopping, exploring MK leisurely, etc. If a guest doesn't want to do LL$, there would be ways to work around that too. Of course, we'll have to see exactly how this all pans out. But this is one potential plan I came up with while I was taking notes during the training yesterday.
