To make the panoramas truly practical as a build goal, without making the game stagnate while players try to collect pieces before building, any packs that enable panorama scoring will need to offer some tools for moving attractions around.
I was thinking about that while printing out the PnP gangsters, since the panorama starts on the very expensive hotels. The only way to make them work is if something allows you to rearrange your park. Would have to be some event card or staff member or resource since another attraction would require you to have only that and the 4 items in the panorama. I suppose the ability could be on an upgrade as well, but I'm having a hard time seeing how that would work.
Of course, you actually need 2 things: a way to move attractions around and a way/reason to score panoramas.
