When I go to enter port of entry/exit/address (these 3 questions) My choice is not there. We are sailing on Princes Cruise Lines to Ho Chi Minh City. I will be there as a tourist for for one day and back to the ship. What do I put as port of entry and port of exit and address while in Vietnam? What else can I say. This is the info that I need to be able to enter vietnam when the ship gets into port. I believe this is kind of stupid to ask for more words when it isn't necessary. {{Redacted}}
