Hi, difficult question. Every track is unique. Here in Italy there are many fantastic hillclimb (Gubbio, Ascoli, Verzegnis...) If you are planning to visit Europe in 2020 i think you should go to Braga, Portugal, for the FIA Masters on the track of Falperra. Very spectacular track and many great cars!
They can go up and down, with their private cars, the days before the race. They can watch some videos, speak with more experienced drivers. Than they have 2 practice session on Saturday and 2 races on Sunday.
