PJCC Brides - Directional Cards

For those of you who have had your wedding or are planning on having your wedding at the PJCC (Lombardi's on the Sound), did or are you making your own directional cards???
I was going to use the ones they provided, but also put a business size card or something like that with direction tips on how to get there, b/c it can be very confusing.
Just wondering if anyone has anything saved that I can review or info on what they did.

Thanks!
