If you loved the FP+ system and used it well (we'd easily did 8-10+ per day) then you will be disappointed with
Genie+. It is not flexible and it's clunky software. Once you get used to it hopefully you can get more than the 2-3 they predict you'll get. I think it has value at MK and DHS and if you are a Hopper. Do I like it, no because I think it's an inferior product compared to FP+ even without the 3 in advance plus you pay for it.
BUT DS#2 just got back from both ...
... Disney using Genie+ with Hopping and buying ILL
and
... Universal with hopping and top Express Pass
He was disappointed with Express Pass and felt ripped off when comparing to what he was able to do with Genie+. He thinks Disney offers a better product but don't tell them because they'll raise the price up to a crazy amount. I'll just keep complaining about it to them in surveys.
I mean it's not as good as what they had.
