I'm considering taking the family on a day trip to New York this weekend. It's about a three hour drive from where I live (am I crazy?). Not sure what we're going to do, but I was thinking about the usual touristy things like Rockefeller center, Central Park, and things like that. We've never been to New York so I'm a bit clueless. Can any of you folks reccomend a good place to park that is centrally located to these things and perhaps reccomend some things we may do/see. I've got four kids so cheap/free is good. I know this is a pretty vauge question so thanks in advance for any help.
