Finally booked this for 5 nights in August '25 and quite excited to go.

Do any locals/Crete professionals have tips on small excursions to do around the area? Mainly looking for half-ish day type stuff so we can spend majority of the time relaxing.
-I've looked at a Nostos Cruises tour that goes up to Spinalonga but it appears they only do tours on our two travel days (Sat and Thurs). Any other recommended boat tours?
-We are interested in doing the Olous scuba guided tour, wondering if it's worth it.
-Also looked at the Little Train Tour, perhaps to Ellinika.

Cheers!
