@Chantal482 you want to cancel bookings or decline requests? If you just decided that you want to host guests only staying for a whole week and you want to cancel those staying for 3 days that is a bad idea, the dates will remain blocked, you will be fined and you won't be able to become superhost. You can change the settings on your remaining dates and leave the reservations as is. You should have changed the settings sooner if you knew that those are the settings you want to go with for the summer. Maybe try contacting Airbnb, but don't cancel yourself
