Hardest MK World P Switches

What do you think are the hardest P-Switch Missions in Mario Kart World?

My personal hardest is "Board a Chartered Flight to the City" in between DK Spaceport and Crown City.

Any of them that say “special challenge” or smth like that in the name

FOR SURE THE HARDEST P SWTCH IS:
Take a tricky tour through shy Guy Bazaar!

It is really long and has so much rail riding and wall riding and charge jumps that it's really tough. Also if you mess up you basically are over since the timer is so short.
