So, these guys from "Ultima Expeditions" finally got back to me.
https://ultima-antarcticexpeditions.com/They fly down from South Africa and offer a few different expeditions, with 2 of them being right around what should be longest day of year in Southern Hemisphere, December 20-21. Unfortunately, the longer trip costs $85,000 ("all inclusive" ... not sure if that also includes airfare to South Africa from wherever). There's a shorter one (36 hours) for $16,000, which would be affordable, but not sure if you could do what you needed there in 36 hours. In both cases, you might have to figure out how to make your observations within the context of whatever they have planned. What's interesting is that the $16,000, 36-hour, trip they bill as "overnight", being not sure what that means since it's supposed to be 24-hour daylight on those dates down there. Given what's going on in South Africa, just going there as a white man might be more dangerous than the flight and crawling around in ice caves. Given that these guys can do 36-hours for $16,000, not sure why the "Final Experiement" clowns were trying to charge $35,000 ... (not counting flight from your point of origin, etc.) ... except as a deterrent against too many people being able to go.
Perhaps if someone wanted to or was able to go down there, we could take up a collection to help fund at least the $16,000 trip. Of course, that same money could probably build a church for the Nigerian fathers, so there's that too. I'd probably have a hard time collecting for this when others could use the money more ... but that's just how I am.
