We just had a question on email that I have never had in 26 years of answering questions about Belize! A cruise ship passenger wrote and told me that the cruise ship company told her that she only needed her birth certificate and passport, and she is requesting confirmation from me. Is that true? Even if they go to Altun Ha for example, they don't need a passport? I am quite surprised if this is so. Can you Belize experts enlighten me?
