Here's a positive thought about the complexity of the new Genie/G+/ILL$ system: The more complicated it is, the less likely it is that an unprepared guest will know how to use it or even know that they can use it. Therefore, for those of us in the know, we will have a distinct advantage, much like the advantage we had with FP+.
It was my experience that a heckuva lot of park visitors didn't know how to use FP+, didn't know they could use it, didn't know it existed, didn't know it was free, etc., etc., etc. Despite the fact that WDW resort guests were always informed about FP+ after booking and many times after that--especially on the day they could actually start booking FP+s--yet many people weren't taking advantage of it.
I expect Genie et al. will be the same. Those of us who've studied up will have an advantage over the people who don't know, don't understand, or can't be bothered.
Does this mean that I like that it's so complicated? No, I do not. But I also suspect (and I hope I'm wrong) it's possible there's an underlying reason for the complexity, and I won't be at all surprised when, a few weeks or a few months from now, WDW starts selling something like Uni's FOL pass and charging $250 or $300 per person, per day for it. It will be simple and straightforward: Ride everything everywhere with instant LL access. Ride as many times as you want, with the exception of the headliners, which you can ride only once. Period. Besides the convenience, the simplicity of this will be a huge selling point. Would I buy this? Certainly not.
