Round 1: Getting in
Draw
The Azores: an ID card is enough. An autonomous region of Portugal inside the Schengen area. Domestic travel for Portuguese citizens; other EU citizens travel on a national ID card or passport. Madeira: an ID card is enough. An autonomous region of Portugal inside the Schengen area. Domestic travel for Portuguese citizens; other EU citizens travel on a national ID card or passport. Same country, same rules: a Portuguese citizen needs nothing, an EU citizen an ID card. A draw, as it should be.
Rule: Fewer hoops wins: ID card, then visa-free, then on-arrival permit, then e-visa, then consular visa.
