Today's Groupon is great for the kids (and young at heart) - 56% off 2 three-attraction passes with 20 arcade tokens!
The regular retail is $39 for the 2 passes and the Groupon discount makes them $17 for the 2 passes. I already bought mine and my kids will be thrilled when they find out.
The passes don't expire until 9/11/10 so you have all summer to use them.
Happy go-karting, laser-tagging and putt-putting!
