At 7 am, open the my experience app. Open my genie day, open tip board. At the top you can pick your park, for example Epcot. It will show what is available. Click on what ride or experience you want. You won’t be able obviously to secure that choice right now but it definitely helps knowing the process. Just remember if you don’t see something available refresh your screen. It not that hard remember that you can make your first selection at 7 am. You can make a
Genie+ and LL. Since the parks open at 9 am you can’t make another selection until two hours after the parks open.
Go on to You Tube, find Resort TV one and look for his Genie + video. It will help you a lot. Hope this helps.
