Hello
I will be coming to Playa in just over 3 weeks time from the UK

and am a little confused over which currency is best to use......I've heard so many different stories.
I hear that you get further with your money if you use the US Dollar to pay for things e.g tipping, as I am staying at an all-inclusive, but just don't know what the locals actually prefer when you pay them for goods etc?? I would like to get all my spending money converted before i come into just one single currency to avoid confusion when working things/prices out but am not sure whether to go for the US dollar or the Peso???
Any help would be really appreciated
