By default, your website allows the guest to edit arrival and departure time from their Reservation Page. So, if you want to hide this option, just follow the steps below:

  1. Access the [Settings] menu;
  2. Find the [Guest Settings > Permission] option;
  3. In the [Will the guests be able to set the check-in or check-out time for the reservation?] section, check [No];
  4. Save the changes at the top right of the screen.

Now that you already know how to disable the editing of arrival and departure time by the guest via website, how about checking out more related subjects?
