I mean, I'm with you with all of this. As a "planner" I enjoy doing all the work before hand so my vacation is predictable as you say. Genie+ is essentially the antithesis of that. I want the vacation
@Jrb1979 wants but I realize I have to schedule parks/meals and previously rides prior to arriving and I don't mind doing that.
That is why I'm baffled. The "planning" isn't really that much work outside setting up some tentpoles for your vacation and working around them.
For me, it is a mix. I'm not opposed to general planning. I have, at times, booked trips early, bounceback offers sometimes meant giving WDW a small deposit a full year out. So those were the visits we ate at 'Ohana.
Have you ever suffered a flight cancelation though? Cancelations are quite common in winter. They can easily = getting stuck in Orlando for an extra 1-3 days.
In the not-so-very-distant past, adding an additional day was restriction-free.
There have absolutely been times when I considered a last trip to WDW (less than 30 days), but then decided it wasn't worth paying WDW prices if I couldn't eat at a certain place AND faced reduced-odds of getting decent Fast passes. Under those circumstances, we opted to go to Universal (or some other place).
I also, I dunno there are many times I was in FL, and planned a dinner, but then something happened and I no longer wanted to trudge from my hotel room all the way to the World Showcase. Like maybe a twisted ankle, or we were tired and napped, or someone didn't feel well.
So every non-refundable add-on bites, because it increases odds I'm going to lose money.
G+ is also even more: you pay but it only= MAYBE you get a fastpass? In my book, that's a scam.
