Hello, We are going to Athens, Santorini, and Sifnos in mid July. Should I always bring my passport with me instead of leaving it in the hotel in Athens? and how about Santorini and Sifnos? I was thinking leave my passport in my luggage in the hotel.
I also saw that US citizen doesn't need a visa, and ETISA is not online until 2026. Is there another online system that US citizens need to fill out, or I can just land in Athens with my passport?
I bought the Acropolis ticket for 8 am. How long does it take to see all the sites in Acropolis? Since the Acropolis Museum ticket is also timed, I'm not sure if I should by 10am or 11am for Acropolis Museum.
Has anyone purchased tickets from Epicurus Festival? I want to go to the concert in the Odeon of Herodes. But they either don't have the 'Buy Ticket' button, or the button doesn't work. I emailed them but never heard back from them. Here is the website: https://aefestival.gr/schedule/?lang=en&?category=&place=136&schedule_year=2025
Sorry for the long questions. Thanks so much!
