From what I understand Mystery park closed down some time ago. You can still see the tacky completely foreign looking buildings there. Yes the cheap commercialism really irritated me as well. I guess money is king.
My original roots are in the Himalayas and I personally feel at home in Switzerland as far as nature is concerned. What I find most amazing is that mountains back home were in the 7000-8000+ meters region compared to Jungfrau which is only 3500-4158 meters high

Jungfrau does not even feature in the top 100 highest mountain peaks of the world
As far as access is concerned Jungfrau probably wins hands down. Definitely an amazing engineering feat! Once we got on the actual glacier the typical tourist crowd disappeared. We walked for hours on the ice away from all the Bollywood and Japanese/Chinese/Korean crowd. Bless them all but we wanted peace and quiet with mother nature.
I am still very ill and stuck to bed. Fever is not in the 40°C region anymore but still constantly around 38.5°C. Feel like a wreck and dizzy all the time
