Question First Time in Greece: Itinerary Help!

I'm planning my first trip to Greece and I'm super excited! I want to start in Athens and then head to Naxos, Paros, and finally Santorini before returning to Athens for my flight home. Does this sound like a good route? Any tips on must-see spots or local foods to try in these places? Also, how’s the ferry system for island hopping? Would love to hear your experiences!
