With the 24/25th being days people are going to OSH I was wondering
whether that would have any influence.


Not in Milwaukee approach airspace. There'll be more traffic for ATC to
deal with, but not a lot more. The IFR routes to OSH don't go through
Milwaukee or Chicago approach, they go around them. The OSH bound traffic
that Milwaukee approach has to deal with originates in Chicago approach or
Milwaukee approach itself. EAA traffic has more impact on the MKG and MSN
TRACONs than Milwaukee.
