- Awful experience here after a day at The Children's Museum! We were charged $38 even though we got our ticket validated and it should have been $25. We tried talking to the parking garage attendant about it and he basically told us "too bad" and was extremely rude and provided no help whatsoever. We notified the Children's Museum about this issue and they were very apologetic and said they'd follow up with the garage. If this happens to you, please speak up! Also call this number listed at the garage and demand to speak with someone in charge 617-268-2604
