You can just walk in when there is not a service. The staff is very friendly and welcoming. It is small but the stained glass is pretty and very vibrant. I was in and out in < 10 minutes
Statue is easily accessible and right on the sidewalk
I was pretty disappointed. It is very small barely three rooms. Everything was very fake and hoakey. I was only there for about 20 minutes. Admission was 12$ I would've done it for 5$.
