5-10 minutes

I don't know why you would want to do only one day if you travel from Bloomingdale WA or Plano, TX. There is so much to do here you could easily spend several days in the area and to spend the money traveling does not make sense. Perhaps you have a long layover at BWI Airport so if that is the case, you can take the light rail to the Convention Center stop and go right from there. There are free color coded buses that could get you there or near there. I would check on the internet about the public transit in Baltimore and you will find a route map for Fells Point.

I'd agree, just about a mile to Canton Square. You can walk the promenade (it gets a bit tricky to follow at one point), but it goes right along the waterline for the most part. Very safe in the day, maybe not as much at night.

We only ever water taxi in.

Try Groupon or Living Social for coupons or if you are traveling weekdays before 7 pm, try Harbor Connector for FREE. Google harbor connector or charmcitycirculator. Enjoy Fells Point!

Agreed, the pub tour would be the way to go if you are "kid free". And Fell's Point is a fairly compact area and very "walkable" so that you can visit things you may have missed on the tour. A helpful hint would be to stop at the Fell's Point Visitors Center as they can provide you with a wealth of knowledge about the area and also have some interesting historic displays.

Depending on where you are walking from, it is not a long walk. We stayed at the Four Seasons in Harbor East and could have walked to Fells Point in 15 minutes. However, we wanted to go to Fort McHenry first so we took the Water Taxi.
