I am using it on ANightInBurlington, but I’m currently in the middle of refactoring a lot of the code. I originally came up with a very clever use of Pages, page templates, and ACF, but I’m now adding custom post types to organize the data a bit more.
Either way, while it may not be visible in the current version of the site, ACF has proven extremely powerful, and makes custom meta boxes / information for anything a breeze.
