I never had a problem keeping things in mind for the South Park games, remembering most of the areas doesn't seem that complicated. On the other hand, I also wouldn't have a problem with the game including a way to skip this content if there are people it truly seems to annoy. I mean, I spent $80+ on the game and the season pass; I feel like I have a right to play it the way that is the most enjoyable for me. Others should have that same right.
Take out all the side quests, though, and you have a pretty sparse game.
