Such a great value if you get a membership! During the summer there is often a living social or Groupon for a family pass for 4 for about $40 to give unlimited general admission from memorial day to labor day. This year when we turned in our Groupon they gave us the option to upgrade to a year long membership for an additional $40, which is still much less than their typical $145 family membership!
