set check in day

I only want to let my guests check in in summer on Fridays. But despite the help content (see below) on this subject, I don't find any button that says 'no arrival' (on all other days in my case). It is really stressfull because people are booking and I can't change it. 


help contnet doesn't march with my pages and lay out actually, strange

If you want to close your property/rooms to prevent arrivals on days when you’re unable to check guests in, you can set up a No arrivals restriction. Just log on to the Extranet and these steps:

  1. Under the Rates & Availability tab, click on Calendar and you’ll see a list of your rooms next to a range of dates.
  2. Click on the drop-down arrow under the room rate you want to apply the restriction to.
  3. Under No arrivals, click Edit.
  4. Select a date range or specific days of the week that you want to make unavailable for check-in.
  5. Under the room name, select I don't want guests to check in on these dates and click on Save changes.
