This season is, as some critics say, more monotonous, and more focused on various sites and landmarks. The girls are forced to grow up due to having an expensive hobby and having to manage the alcoholism of their supervising teacher, which is just sad and pathetic, though the show tries to show it in a comedic light, which pretty much fails. It's just tragic if you give it a closer look.
It's good that the show included some depiction of Rin's fatigue, as she crammed a lot of activity in one day, though I understand that it would limit what they could show.
There is less actual camping, and more sightseeing. Setting up camp is now rarely seen, and that's a bit annoying.
