You go in the evening from 4 to 9:30 p.m. the price is $20 per person and very worth it it's fun for all ages
Try Groupon
I believe all day is $40 / person. Look on groupon and see if there are all day tickets. I was able to get them for $30. Make sure it's the Danvers/Boston location.
Anytime good try look for deal on groupon...also buy ticket in advance to skip big lines...u can carry ur food...
