Hello @David4610 and welcome to CC youwill find very helpful information in here if you use related keywords in the searchbox.
Have you looked up under Help Section at the bottom of your page?
There's a separate part for times on your ""Dashboard which shows the arrival and departure times, I've mine set as an example as Flexible "check in" for arrival and 10am for my "departure" time.
ABB have a standard 3pm arrival time so be clear on boundaries for your own benefit.
Remember to take into account time you need for cleaning between guests and for those who are booking to be aware you may have an existing guest so they may not be able to check in until the other person has checked out. Food for thought for you!!
Happy Hosting.
All the best from New Zealand
