Hi, I am from the UK and do not have to have any documents translated. I just need to show my passport and tourist card (which you are given to fill in on the plane) and you have to have blood tests in resort. From what I can gather, if you were adopted, have been divorced or have changed your name you will need to get certain papers translated but if you let your wedding coordinator know if this is the case they will tell you exactly what you will need to do.
