They no longer sell tickets that include
Genie+, so you will have to buy your Genie+ and ILLs on a daily basis. A park hopper ticket makes sense and can help you in stacking Genie+ reservations for later in the day.
HopperFan gave you the link for the Disney official website explaining Genie+ and ILLs. The main Disboards thread discussing it can be found here:

In addition to Genie+ and ILLs, you may want to figure out how the Virtual Queue for Guardians of the Galaxy works. Although that may be gone by January. it might be replaced by a Virtual Queue for Tron by then. They haven't announced when Tron will open, but you might get lucky.
Also, look into park reservations and mobile ordering. In general, you may find this thread useful:
