Getting here by train: There are trains that run fairly regularly between Toronto and Kingston and between Montreal and Kingston. See the VIA Rail Canada website to check schedules and make reservations.
Once you get off the train, get a taxi to take you to whichever residence you have reserved a room. This should suffice for the cab driver. If not, then the addresses given on the lodging page should get you there.
Getting here by car: Residences are on Stuart Street, Bader Lane, or Lower Albert Street. I will give directions to these locations.
I assume everyone driving will arrive via Highway 401. Take the exit for Sir John A. MacDonald Blvd. Follow Sir John A. MacDonald almost until you get to the lake, then turn left onto Union Street. (If you end up in the parking lot of the Kingston Penitentiary, then you have gone one block too far.) Drive on Union for several blocks. Turn right onto University Avenue. Drive to the end or near the end of University Avenue, then turn right onto Bader Lane or Stuart Street. Lower Albert Street is at the end of Stuart Street. Bader Lane and Stuart Street are quite short, so you cannot lose once you have found them. Information about parking is available on the lodging page.
