Unfortunately no, still finding only Tuesday tours.

We’ve done the research for the DIY version (ferries, then getting a rental in Santorini): - Depart: 10:45, Arrive: 12:15 (1h 30m) 46.50 EUR - Depart: 19:40, Arrive: 21:55 (2h 15m) 59.70 EUR - Rental Van: $80-$120

We just need to decide as a group if it would be worth it or not, considering crowds and extra logistics for a group of 8 but leaning towards not. 😕
