There's a parking garage next door, but depending on how many people are driving to your wedding, it might not be enough space (though other larger garages exist a few blocks away, too). You might want to recommend guests with cars take transit into the city, or keep their autos parked at their hotels and take a Lyft or Uber to the wedding; then they don't have to worry about designated drivers, either. Talk to one of the hotel's event coordinators, they should be able to give you the best advice.
I took Uber.
