If you’re in the Chicagoland area, here’s a great deal that you may want to pick up! Groupon has a deal right now where you can get an Exploratorium Pass (located at the Skokie Park District) for only $13 for residents or $24 for non-residents. Each pass allows 10 entrances, so you’re looking at $1.30 per visit or $2.40 per visit respectively. That’s an excellent deal! I’ve been to the Exploratorium with my kids a number of times and always have to pull them out kicking and screaming hours later (okay, not literally, but they never want to leave!). The passes don’t expire until 12/31, so you should have plenty of time to use it! Limit 1 per person.
