The Duggars were shown at the Creation Museum on an old episode of x Kids. Jana even admitted that evolution had some "good points." This was before the Ark Encounter was up and running, but I'm sure the Duggars have visited since. But yeah, Ken Ham made a guest appearance.
The debate between Ham and Nye was classic. Nye killed it! 😁
Independent Lens showed an excellent documentary on the opening of the Ark Encounter, narrated by a guy who once worshipped Young Earth Creationism and Ken Ham. I wish I could remember the film's name, but I saw it about a year ago. If it comes to me, I will definitely post it because it's worth watching just to see how these people - some of them with doctorates - operate.
