Disney are so odd sometimes, its like they enjoy creating artificial demand for their products which allow people to sell on to others at a profit. The eBay Scalpers are providing something that Disney is not.
Why not let people stopping in the hotels get them pre-booked so they are waiting in the room, and you just need to get it filled up. Why does Disney not sell them online, so people can order them and get them delivered? Why not have several kiosks selling them? I guess if they did that, they would not be limited, and people would not want them?
I like the idea of not knowing about something special, and stumbling across it and been wowed by it as part of the Disney Magic, but the idea of doing that these days is impossible due to the internet and once the secret is out, everyone knows about it. You have just been on the Figment ride, your exiting the ride, and you fancy a snack, and you spot the Figment Popcorn bucket, and you have that bit of extra magic.
If you got more people paying $25 for a plastic popcorn holder, they could maybe not rely so much on selling the Disney Genie+ for additional revenue.
