There is a public parking lot behind Kidcity. Parking is $1/hour and the meters charge from 8 am to 8 pm, Monday to Saturday. The meters take coins, credit cards and payment from the ParkMobile app (we're registered as Lot# 8204).
By the way, the parking lot belongs to the City of Middletown and they do monitor it!
When the city lot behind Kidcity is full, you can find additional parking in nearby lots on this downtown parking map.
Kidcity is in the big blue and yellow houses at 119 Washington Street, Middletown, CT.
Hint: Washington Street is also Route 66.
