As for moving to Manhattan with a family, it all depends on what part of Manhattan and will you be renting. I'm sure you are aware that the prices in the city are much higher and you do not have as much land for the kids to roam.
You will also want to look into schools, you didn't mention whether your children would be going public or private. Here is a link to research public and private schools in New York : http://www.greatschools.net/modperl/go/NY
I do not have personal experience living in Manhattan but I know a family who lived on Sullivan Street and raised two children there. There kids grew up a bit more street savvy and seemed to be cultured due to the diversity and artistic happenings they were surrounded by.
Good Luck to you and your family.
