Each of the hotel blocks we have reserved are within 1 mile from the venue and rehearsal dinner location! While there is a parking lot we encourage our guests to walk or utilize uber and lyft. Directly across the road of Merrimon Wynne is a large parking lot reserved for the entirety of the event. Rideshares are easily available in Raleigh.
