Absolutely!
Parking is public and free at the Cade Museum (reception)! However, it's a bit tight at the Hippodrome. We suggest the GRU or courthouse parking lot, both of which are free on weekends. If you'd like to be a bit closer, there's a downtown parking garage, located at 220 SE 2nd Ave.
If your invitation says “and Guest,” then yes! If not, we would prefer if it was just you.
Y'all can wear whatever you'd like, we're just happy to have you!
