If you're H/B then usually you'll only need to eat one other meal in the day and you'll easilly do this with a drink for about £7 each! Unless you want lobster or a posh restaurant for lunch! Most places do Chicken and chips etc for about 8 euros and then a drink for 2!
Obviously if you want to drink 10 pints every night you may need more money but if you have 4 or 5 you should be fine!
We usually buy any soft drinks for around the pool from the local shop (even though you're not supposed to but everybody does)
One thing I always do though is make sure theres some cash in the bank, just in case!
Also one thing to remember is whilst on holiday you won't be at home for two weeks so you'll also have that money to spend on holiday, ie no petrol/gas elec etc! And i don't know about anybody else but me and the wife spend about £100 in petrol over two weeks!
