successfully did so 3 times with no tricks or secrets or anything shady. Just opened the door and walked in. Also, way more than half the time I’m able to get into the MC if I try enough doors. Generally I’m with young kids that are dying to see inside, so we’ll go down right into the floor and take some pics and leave. Very respectful, usually really quiet so we don’t disturb anyone, but still we tend to get in more often than not.
