Looking for feedback on our 14-day honeymoon itinerary

Hello! I've searched the archives to see if I could find the information we're looking for, but none that have quite the combo of islands that we're looking at and I would love any thoughts you might have in terms of our timing, planning, recommendations, anything at all!

We're flying into Athens the evening of June 23rd and flying out the morning of July 8th, which gives us 14 full days in Greece with nothing booked yet. Super excited to start planning but go figure the more I read the more confused I become re: which islands to visit (the real answer feels like we need to visit all of them 😅). We're looking for a mix of history, enjoying the outdoors (not opposed to hiking!), and some nice beach time. We enjoy a good time but not big partiers when traveling. Based on everything I've read, I think we're looking at the following:

June 23-26: Athens (3 full days with travel taken into account; looking at a day of inland driving on one of them)

June 27-29: Athens to Santorini, two full days on Santorini

June 30-July 2: Santorini to Milos, two full days on Milos outside of travel

July 3-6: Milos to Crete (thinking of staying in Chania?)

July 7: Crete back to Athens

July 8: Fly home

I think my biggest questions are:

• Does this feel like a reasonable itinerary, or will it feel rushed?
• Does this order of islands feel right when taking ferry/flight options into account? Should we switch the order? What are the best ways to get to each?! Is ferry better for one but flights better for others?
• I think we'll be getting a car for our Athens day inland, as well as our time in Crete, but will we need one in Milos? Am I right in thinking we'd be fine in Santorini with bus/taxi?

Honestly anything anyone has to share, about those questions or more generally re: the trip would be greatly appreciated... my international vacation-planning muscles feel very rusty after the pandemic and I'm feeling pretty overwhelmed with all the moving pieces that come with all the different islands! Thanks so much!
