Spent the day here, because it was another cold and windy day in Chicago but didn't want to waste our time there, so we found indoor activities. It took almost 2 hours with Saturday traffic from Rosemont though.
If you enjoy space and all that goes with it, this is a great place. We attended two movies the Deep Space Adventure with the "Searcher" in the Sky Theater I thought was really well done along with some of the interesting interactive displaces while waiting to attend the movie.
And Space Junk Three D, although I don't care for 3 D movies was very informative and makes you realize that we need to clean up our atmosphere around the earth also. Who knew there was so much junk up there!
Not the type of place I would go back to many times a year, but definitely when in Chicago and you need something to do...
$19.00 to park in the lot.
