When you have a check-in and a subsequent check-out in the same unit or vice versa, you can activate the Change Over Days feature. To do so, log into app.zeevou.com and click on the gear icon and select Preferences. Then, you will be redirected to your Organisation Configuration. Select the Change Over Days tab. If you tick the box Prevent Early Check-Ins or Prevent Check-Outs, you can prevent your guests from early check-in or late check-out.
