Spending money for tenerife, playa de las americas?

Depends where you want to go, if you go to Veroncias and Starco then it's a bit more expensive than bars outside these areas. A pint of beer is about 2.50€ for Dorada, the local beer but it goes up and a pint of Guinness would cost you around 4.50€, the average I guess for a pint is about 3€ and shots around 3€-4€ depending on what you're drinking. 200 B&H cost 24€, a single pack of 20 is around 4€ so best to buy a carton of 10, works out at 2.40€ a pack of 20. I suppose it depends on how much you want to drink! If you plan on drinking 10 pints a day and not eating then 250 euros is enough but you might want to budget something in for food!! Allow about 20€ a day for food too oh and as it's a lads holiday, a trip to Siam park would be a good laugh, biggest water park in Europe! Have fun!
