It’s from a “we’re being charged for something we shouldn’t be” mindset, but it fails to realize Genie does add value to your day at the park compared to not purchasing Genie, you just have to decide whether that extra value is worth your money.
ILLs are mostly worthless, though. If you’re fine with waiting in a couple long lines, or spending the whole day at the parks, you can get on basically every ride no problem.
Rise at park close rarely has a long line, so hopping in a few minutes before the park closes is relatively painless. There’s always the risk Rise breaks down late in the day and doesn’t re-open, so if you have a must do attraction, do it early.
Same with Flight of Passage at Animal Kingdom.
Essentially, try to avoid buying ILLs as much as possible, but Genie is generally worth it.
The issue is, if you’re paying $100 a day in tickets, and you ride 6 attractions, you’re paying $18 a ride. If Genie gets you on an extra 4 attractions, even if it costs an extra $15, you’ll be paying $15 per ride on average, while getting an increasingly enjoyable experience.
Obviously, fun exists beyond attractions at theme parks, but regardless. If you don’t go often and want to maximize your time, it’s probably worth it.
