Bumped my review up a bit.. After a few weeks and emails, we were contacted by cmfdl. They were very kind and friendly, and thanks to their generosity, we decided to give it another try. This time, we stayed for several hours and my son had a blast.

Original Review: We arrived at 10:15 only to find out there was an event going on. Because of that admission was $2 extra per person. What they didn't mention was that they were closing at 11. Hours were listed as normal and the event wasn't mentioned anywhere (website, Facebook, etc.). We paid extra to be kicked out 45 minutes later. They should have had these hours posted somewhere and they definitely should have mentioned this to us before we paid to enter. Our son was super sad and disappointed to leave so soon.

Being our first time here, I wasn't super impressed. There are some cool things to do and our kid had fun, but the museum in Appleton is worth the extra money and drive.

ETA: It is listed on their website, but not under the events on the homepage. Partly on me for not noticing there's another events section (Classes/Programs/Events) but they should have said they'd be closing in 45 minutes. We'd have gone elsewhere.

ETA2: Dropped to 1 star. I contacted them about the experience and didn't hear back at all.
