Come back and visit soon!
Being a native of East Norwalk, personally I feel that it's thebest part of Norwalk. You can walk/bike to everything and it is like a community unto itself. Yes, everyone here is friendly....we live in a beach community...we're happy!
Anyway, no, you cannot choose the schools the public schools. It's all based on where you live. The schools that your children would attend in the East Norwalk area are Marvin Elementary, Nathan Hale Middle and Norwalk High School. There is also All Saints which is catholic school (tuition) grades K thru 8.
As far as ascension beach club, it is owned by the same family as Cove Marina, the Gardella family. You can call (203)838-1002 for the costs. I know they are very reasonable and a well run beach club.
Good luck. If you decide to look for real estate in the Norwalk area, I would welcome the opportunity to work with you.
