Hi mr maclean, firstly be careful in some of the ports in south america that the ship calls in, try and go ashore either in the shuttle bus ,or if walking go with a crowd. if the ship retains your passports, make sure you have them when you go ashore or you will not be able to change any money or travellers cheques without a passport, in rio go into the port terminal to book a days trip in an official car to see the sights(sugar loaf, christ the redeemer etc )very good value,regards
