How to compare Greece travel agencies
Ask for a sample itinerary in your exact season, who meets guests at each airport, and whether one invoice covers all bases or partners are subcontracted. Strong Greece agencies disclose balloon, permit, or museum windows—not generic “full day city tour” lines.
Trade buyers should confirm net-rate policy, payment terms, and whether the agency holds incoming tour operator or DMC registrations relevant to Greece.
