Just got back from a trip. We spent two days in each park and only bought Genie+ a couple of times. Bought ILLs a handful of times. But, really, we didn't have any problem doing every ride we wanted to do, even when we didn't buy anything. The longest line we got in once was for Rise of the Resistance. Standby said 80 minutes, but it was actually only 45.

However, this was a mid/late August trip and crowds were very manageable. I don't know if this would be true at the peak of summer.

And, at every counter service there were regular ordering lines. If we didn't mobile order, we had no issues getting in a line and ordering in person.
