It is very important before the trip to identify for yourself the purpose of your trip. Conventionally, Crete can be divided into "beach" and "excursion". Those who want to lay flat on the sand, sip on a cocktail, and smear on sunscreen/sun cream will have a great time.
I have never had such trips. 10 hours before departure, and my things are still on the shelves, there is a mess in my head, the hotel is not booked (I forgot), my ex-girlfriend has a suitcase, a friend has a camera, etc.
