There are multiple parking garages downtown Frederick. The two parking garages that are closest to our venues are the Caroll Creek Parking Garage and the East All Saints St Parking Garage. Sometimes you can find parking in the street but be aware of the signs delineating which days and hours parking is allowed.
There are several 3-star hotels about 2-3 miles from downtown. There are a couple bed and breakfasts downtown but may be booked so check early. I would recommend an Air BNB or VRBO downtown for close proximity and easy walkability to the festivities! There are several beautiful, private homes/apartments to rent for the night or the weekend. Derek and I have rented and stayed at Air BNBs in downtown Frederick multiple times and have always had a good experience. One owner even left us each a free Frederick pint glass!
