Looking to go to either Baltimore or Boston for my bday weekend in June. It will be 4 girls total. Nothing fancy needed. Just looking to eat/light sightseeing/explore the city and visits some parks or fun interesting places. Please help me decide! We love seafood and both seem like really good places for seafood! Any suggestions? Where should we go and what should we do? Forgot to mention we are traveling by train or bus so no car! So is this an easy walking city to get around?
