I am driving in to the theatre from RI, any parking garages nearby?

Yes, but it is NYC, so plan ahead and to pay top dollar.

Check the discount parking apps. There are a ton of them in the theatre district

Yes

I use the self parking garage in dyer ave off 42st , its the safest lot, near by walking distance from the theater , inside parking so your car isn't exposed to the public, rest room on the way out,

Yes, right on either side of the theater, but if you park there it is over $50.
