I have to go to the parks after 5 pm, after attending a conference. How do you suggest I utilize Genie+ to maximize big rides? Long time Disney fan but this is my first rodeo with Genie+. Thanks for your help!
For the ILL$ attractions, you can choose the time you want, and these are independent of Genie+.
For Genie+, you will be stuck with the earliest available time. For AK, you won't find any times after 5pm until late in the day, and for Epcot, Test Track is the only one that will have post-5pm LL time for bookings during the morning or early afternoon.
Right now at 9:45 am, Jungle Cruise is your only post-5pm option at MK.
HS is your best option. Get Slinky Dog at 7am, and get Millenium Falcon at 11am (if still available). By 1pm, Rock n Roller Coaster, Tower of Terror, and Toy Story Mania should all have post-5pm times.
