Great experience. The staff was welcoming and extremely knowledgeable. The entire family loved the planetarium shows and exhibits. The Mansion and grounds are gorgeous. Beautifully kept. Staff is courteous and educational. Would definitely recommend for the entire family. A beautiful scenery overlooking the Long Island Sound Northport Bay. Great place for a picnic or a wedding 💒
