Fyi: Baltimore has free bus service on 4 routes that depending on what you are doing can save time and money with trying to park at certain places. It's called the Charm City Circulator and consists of four separate routes—the Green Route which runs from City Hall to Fells Point to Johns Hopkins Hospital Campus, the Purple Route which runs from 33rd Street to Federal Hill, the Orange Route which runs from Hollins Market to Harbor East and the Banner Route which runs from the Inner Harbor to Fort McHenry. The HC consist of 3 routes – HC1 which connects Maritime Park to Locust Point: HC2 which connects Canton to Fells Point: and HC3 which connects Pier 5 to Harbor View. A simple google search can get you more information. I never knew about it until my niece told me - she'll attends Johns Hopkins and uses it all the time as do I when I visit.
