I'm tentatively planning to fly into BDL and renting a car for a trip to Northampton. But after returning the car to the airport in the late afternoon, I will need to get to downtown Hartford. I've looked at many websites, and all I can find that is reasonably priced is a city bus with no room for my luggage. I'm a woman traveling alone and would rather not have to navigate steps on a bus and juggling a 24" suitcase plus a back pack by myself. Are there any other alternatives that don't cost a fortune?
