Thanks for all the feedback, I guess SFMM is the obvious choice for one day, but...

Honestly you could probably fit SFMM and Knotts into one day if you so choose. Hit up Knotts early, stay there for 2 hours and ride all 3 rides, then leave to get lunch and then hit up SFMM for a few hours. SFMM tends to empty out a bit in the evening, especially in July/August, so you should be able to get in Tatsu, X, Goliath, Riddlers, and Scream,if not more.
thanks for this idea too. If I get a Valleyfair season pass again this year (which may or may not happen) my brother and I could get into Knott's for free.
Another question, how far is it from Knott's to SFMM if we did do the one day thing?
