We have only cruise the Caribbean and the only except to having to show both Govt ID and ship card has been at Costa Maya, Mexico. Every other port we have been asked for both. It is no problem carrying our driver license with our ship card. We don't bother with passport as we always know what time to be back on board and are on early. The times we have taken excursions not with the ship they have always been in the morning and for no more than 4 hours.
