You may want to budget for eating out each evening and for a snack at lunch time. A light vegetarian meal with a fruit juice could be as little as £3 whilst a seafood meal with a couple of beers may cost £12. You might need around £200 for food for the holiday, plus money for shopping, and trips.
You will also need cash to pay for massages and treatments. If you have a full course of Ayurvedic treatments, you should budget about £190 (€270, $300, AUS400).
