Groupon to the Grand Rapids Public Museum! Admission is normally $8 for adults and $3 for kids, so this is a good savings! PLUS, it includes a carousel ride and a planetarium show for up to five people!! That's like a full day of fun for $20.
I'll let you in on a little secret. Anyone who lives in Grand Rapids can get in for FREE at the Public Museum every Monday (even holidays!). So, I would probably use this Groupon to get another family in for cheap while my family gets in free. OR, you could invite another family, use the Groupon for the adults, and pay a lower price for the kids to get in. Any way you shake it, this is a good deal. My kids love going here to check out the animal exhibits, the big whale, and the giant clock. :) Go here to enter your email address and get started!
