Want to hit up CoCo Keys in Danvers? Get $10 off your day pass by using code COCOWEEN09.
THIS CODE IS GOOD ON THE HALF DAY PASSES - those cost $25. So you can get in for $15 (I think the hours for the half day are 3 pm - 9 pm on certain days). Not too shabby if you are looking to water park it up in Massachusetts. I'm not sure how long this code is good until.
