Groupon:Adler Planetarium memberships Posted on November 22, 2014 by The Goddess After seeing the admission costs alone to get into Science and Industry yesterday, I am more than ever convinced that yearly memberships are the way to go…well, up to a point, the point being grab a deal on them! Choose Between Two Options: $59 for a one-year individual membership, valid for one cardholder and one guest ($89 value) $79 for a one-year family membership, valid for two cardholders and all children in household ($129 value)
