For Xmas 2018, we planned to visit our cousins in Kakinada. Kakinada is a coastal town right by the sea. It was a 4 day trip, and my first to Kakinada. Ideally, had it not been to visit my cousins, this could easily have been a 2 day weekend trip. We left by train (Cocanada Express) from Hyderabad, and reached Kakinada in the morning. As stay was at our cousin's place, we did not incur stay cost. Having said that, there are plenty of good stay options in/ around Kakinada.
