I'm starting to plan this summer's family boat trip. Any recommendations of transient marinas in Essex Conn., Mystic Conn., and Newport Rhode Island would be much appreciated. We need marinas that are better suited for younger children that may include a pool and other activities. It would also be helpful to be located close to area attractions that are either walking distance or a short cab ride away. Any information about the above locations as well as water hazards, tides, and currents I should be aware of would be helpful.
