@Helen3 Snoozing do not solve a problem of existing reservations.
"Snoozing or unlisting your listing doesn't affect your confirmed reservations. To deactivate a listing, you'll need to complete all current reservations."
I have 2 reservations from Canada and 1 from France. The penalties are:
"If this is done prior to seven days before the guest is to check in, then the penalty will be $50. If the proprietor cancels within one week, there will be a penalty fee of $100."
And I will lose my super host status.
So far EC includes only Italy, US, China mainland, and South Korea. So no, as far as I know, I can't cancel my reservations without paying penalties and loosing super host status. I blocked my calendar till the end of July, but still my problem are upcoming reservations.
