If my choices are July 3, 4, or 5th, is there a best day among the three days to visit Shedd? Tue, Wed, or Thurs? Also what is the best order to see everything. We plan to get there early and buy tickets in advance. I'm trying to nail down dates so that I can start to buy tickets. However, S & I isn't even selling Coal Mine until March 15th, so I will wait until then to buy all our museum tickets.
