Feedback on 10 day solo travel in Greece mainland

Hi, this would be my first time in Greece, traveling solo from Vienna. Doing mainland only — no islands this trip. Here's my plan:

May 20 – Athens: Arrive 8am, Acropolis + explore
May 21 – Athens: Museums
May 22 – Athens: Day trip to Delphi
May 23 – Athens: Open day (maybe short trip nearby or just relax)

May 24 – Nafplio: Travel early, Palamidi Fortress
May 25 – Nafplio: Day trip to Mycenae (possibly Epidaurus as well)

May 26 – Meteora: Travel day to Kalambaka
May 27 – Meteora: Monasteries + hiking

May 28 – Thessaloniki: Morning in Meteora, afternoon travel north
May 29 – Thessaloniki: Full day exploring

May 30: Fly to Vienna at 8pm (full day free before flight)

All public transport — KTEL buses + trains, no car. Budget around €150–200/day for food + accommodation.

Does this feel well-paced? I would love to get some feedback or advice on things I can add/remove from my plan, and if I am being reasonable about traveling only by public transport

Thank you!
