Not exactly sure on costs of individual costs as we had the meals and drinks put on a "tab" and paid at the end of our stay. but looking at the menus, the prices are roughly 100 - 200 rupees more expensive but when you work it out it's only about £3 maximum, nothing to cry about!
But we didn't want to stay at the hotel all the time. we went on plenty of trips, walks and relaxing on the beach or hotel pool.
as I mentioned earlier, we wanted to try out different places. I would recommend Victors for an evening meal. You can see his shack from the hotel, its on the road to the beach just past all the stalls, which they call run the gauntlet! you'll see why.
You'll have a fantastic time.
