My husband and I are flying into BWI with our son for session 2 summer seminar and have decided to stay in Annapolis for the week. We've decided to use public transportation for getting around as opposed to renting a car. Can anybody give feedback on what is the best transportation from BWI to Annapolis. We are looking at the C-60-bus...but cannot find where you buy tickets. We also see there is a super shuttle. Any other ideas? Looks like we can get a ticket for $16.50 week to ride a bunch of buses
