Hi there! Your excitement for planning a trip to Greece is infectious! For a first-time visit, I’d recommend starting in Athens to soak up the rich history and culture at iconic sites like the Acropolis and the Acropolis Museum. From there, you could head to Santorini for its stunning views and charming villages or Naxos for a more relaxed vibe with beautiful beaches and historical sites. As for guiding agencies, Dolphin Hellas Travel Agency, established in 1970, comes highly recommended for personalized itineraries and local expertise. Another great option is Aegean Thesaurus, known for their professional service and tailored trips. Both are Athens-based and perfect for crafting a memorable Greek adventure. If you’re juggling trip planning with other tasks, you might also find business assignment help services useful to free up some time for crafting the perfect itinerary. Happy travels!
