"Family Day Trip from Cuddalore to Karaikkal: Suggestions and Dining Recommendations Needed!"

I'm planning a family trip from Cuddalore to Karaikkal by car. We intend to visit the Chidambaram Nadrajar Temple, Tharangambadi Fort, and Karaikkal Ammaiyar Temple, all in one day. If anyone has suggestions for additional temples or places to visit along the way, I'd appreciate it! Also, recommendations for a good hotel to eat would be great. Thanks in advance!
