Fastrack is immorally wrong because the product they are selling is other people's time. Buying a photo is a decision that doesn't affect anyone else, unless it isn't your photo...
However from a business perspective Fastrack is very profitable and so unlikely to go away. Anyway there are a few good uses for it, for example if you are only able to visit a park once and so purchase Fastrack to make sure you get on everything that seems like a good enough reason to me.
However this is all beside the point. This will not be a Fastrack kiosk as Adz has very kindly informed us that it will be a theming addition. Adz generally knows what he is on about in these matters, although I expect that is all he can tell us. I say good on Merlin for doing this. I still wish they’d make more post completion changes to rides that have been around longer than this year but this is a good sign that they are willing to make such additions.
I wonder if the location being under the lift hill is relevant
