I have tried to bid a better than or equal to 3* Hotel in Boston for several weeks. My aim locations were Boston Downtown areas such as Theater district, Quincy Market Financial, Aquarium and Back Bay since I am a foreign traveler with my family. Everytime I stopped at $150 for 3*, $170 for 3.5* and $200 for 4* for those Downtown areas. Maybe that's the busy season in boston during May? Today, after many many fails, I just want to try my luck in other areas. So I put $150 in Cambridge West - Harvard for 4*, and get the Hyatt Regency Cambridge at my 1st try ! The hotel seems located far from Boston downtown and with a high price? But I am still quiet satisfied with this result. Here are my other questions: 1. I will take a 2-day trip in Boston for Harvard University, Public Library, Quincy Market and maybe take the Duck Tour. Any other suggestions? 2. And basing on my trip above, should I rent a car (Travel with 5 people in total) or take the T ? I'm worried about how is the traffic and parking in Boston Downtown? I will be really appreciate if someone could answer my question. Thank you very much !
