Yes, you won't need Genie+ for the two BG rides. To get on them you have two choices:
- Enter the free lottery
- Buy a LL$
Neither requires G+$.
Correct. If you're in the park at 9 AM and open up Genie and you purchased Genie+$, then when you scroll through available rides, you might see that PPF's next LL is at 10:15 AM. You don't get a choice of times. You just hit that LL button and you're now scheduled for PPF at 10:15-11:15 AM.
If you tap into the LL at 10:15, you will then be able to chose your next LL from G+$, which could be, e.g., Haunted Mansion at 12:30p or PotC at 11:20a.
Correct.
