Alpine national park bike tour 444

I am planning to do this tour next Friday to Sunday. On my own. Has anyone done it before and can share their experience with me ? Any hotels near the route you recommmend ? Anyone in Zuoz, Scuol or Livigno area that weekend let me know 🙂 https://www.engadin.com/en/tours/nationalpark-bike-marathon-schweizmobil-nr-444
