I was issued a 3-month multiple entry Schengen visa to attend conference in Sweden in June 2017. I went to the conference and wow I want to visit France with my family. I know my family members will need Schengen visas, but:
Can I visit France with my valid Schengen visa? In the visa, it mentions 'conference' and I've heard that French border officials can be very strict about this.
We all might have single itinerary and hotel bookings; will it affect getting their visas or my entry into France?
