There were definitely choices made to attempt to make the genie plus service work in general. There have to be good rides to pick or it won’t work. Like Slinky Dog is not ala carte!I'm really surprised it isn't as i'd think the target audience for this is families - many with little kids. They chose the rides with the two highest height requirements in the park for Individual LL at DAK.
Although I guess that could be purposeful in the sense that the safari is a family experience and since everyone may not be tall enough or even want to go on Everest, the people that do can pay a little bit of money, maybe on a Christmas week type of day, to skip a long line and get back with the family in a timely manner. But then you are only getting maybe 2 or so out of a family of 4 to buy into this instead of the whole family so once again I don't see how it makes a ton of financial (key word) sense for it to not be KS.
