Velankanni Shrine Booking
Usually, they do not encourage advance reservation. You have to go there in person to the accommodation booking office and make a booking. There is a booking office just opposite the bus stop, take a token and await your turn. If you want to make advance reservation, try VPN Residency, a private hotel at Velankanni. Non AC rooms are available for Rs.850/-. Hotel is close to the shrine and accommodation is decent.
