Driving down to Baltimore from Harrisburg, PA for a quick overnight trip on a budget. Got a room for $65 at the Marriott Inner Harbor at Camden Yards. Unfortunately the parking is $24 a day at the hotel. Was wondering if it would be feasible to park at one of the light rail stations (Hunt Valley, Timonium, etc) for one night. We would be driving in on Friday midday and leaving Saturday afternoon. It would save us about 18 bucks in parking. I've used the light rail on multiple occasions for day trips, but never overnight. If that doesn't work, does anyone have other suggestions for saving money on the parking? Thanks.
