Stayed at the grapevines with an exchange rate of 1.18euro(25-5-08) handed over £10 note to be given 18euros back, with that exchange rate went back for a second time. And yet again got 18 euros, i think you will quite agree the best exchange rate on the island
Would recommend you use the cash point as we were getting 1.44 exchange rate.
On my hols last year (July/August 04) we was charged 143 at all supermarkets!
