I fully anticipate there being a price increase in Genie+ as an app (and the ILLs, for that matter). As much as I dislike paying for what was previously free, by setting the price as low as they have, Disney is guaranteed to end up with ticked off customers when they pay $15/pp and can only get two rides out of it, and likely only ONE of those was a ride the customer really wanted, the other being all that's left. For our family of 5, that $15 would add up quickly, but I would still be willing to spend it. Kick the price to $50/pp and I'm out (most likely) and I think a lot of other people would be, too, thereby fixing the availability issue.It's why they should have went the Universal route and create their version of express pass.
Full disclosure: We are taking our first trip to UO during the second half of our vacation in June (1st half at WDW) and chose to stay in a resort that included the Unlimited Express Pass. Had the hotel not included it, I would not have bought it, nor would I have chosen this hotel.
