Yes Boston rocks! I'm not surprised you asked this after the visit. I lived there for 15 years, left in 2000. Boston may not win the poll but thats because people don't know or havn't been there. New England in general is a great place to travel but the culture in Boston is so rich it is my number one destination to revisit.
I'm from the US, I think it really depends on what you like to do or what you are visiting for. I've been to all the cities you've listed and I think Boston would be a great place for people to go. A lot of history there too. New York City is very different in comparison to the way the majority of american's live, but I think it would be another good place for visitors. Orlando I think is a good place too, lots for kids to do with Disney World being there, and I think it has hte small town atmosphere that most people are talking about Denver having.
Hope to visit NY someday. But it is depends on purpose. I think NY is great for tourists, but I won't choose it as a city of residence. Too big and too many people.
i really liked San Francisco. Suprisingly even Oklahoma City was nice (with it's new canal) I am flying to Miami next week, can barly wait
Yeah...Orlanda is nice, not very known and not too populated...Like Orlando for example... The problem with that kind of question, you'll see people typing their own city. You need to ask people who got there as tourists...
It also depends on what time of the year you go, and what do you want to do there, Denver is nice if you like to enjoy winter sports, New York City is very nice in the spring/early summer before it gets really hot outside same with Chicago. Las Vegas you can go all year around if you like to have fun and party. It just depends on what you want to do there.
I would only recommend New York City. I lived there for 3 years and loved it. It is culturally diversed, plenty of things to see, and pedestrian friendly. You would never get bored ever and it's exciting place to visit.
