Planning a tourism trip (< 90 days) with a friend who has the 1951 Blue Travel Document issued via the UK. On our last trip we went to Italy, which permits her to enter without a visa for a short term stay.
Some other country require a visa to enter (France, Spain, etc). If we fly into Italy and then train or fly to other Schengen countries, will she be allowed to enter? Can we fly out of a country like Spain etc that is Schengen as long as we enter via a country like Italy? Italy will give her a stamp on entry, is that considered a valid Schengen visa for display if we are in other Schengen countries?
