This was a decent outing for us - we didn't love it, but didn't hate it.  We bought the Groupon so in total we ended up spending about $30 for 4 people.  Our kids are 5 and 2.  The 5 year old liked it and the 2 year old was scared.  It took us about 10 minutes to get through the first time.  We would go back IF there was more to do (included in the fee we already paid) and IF there was no candy-wall.
