The call that comes in at two in the morning is a real buyer
A round the clock hospitality economy means standard business-hours coverage discards a genuine share of your demand every week.
Casino, resort, airport and hospital shifts put a large number of valley households on schedules where the errands happen at night. When those people finally deal with the hot back bedroom, your office is closed.
Start by counting what you are missing. Pull the call logs by hour and day, including the calls that rang out and the ones that hit voicemail and produced nothing. Most owners are surprised by the shape of that chart the first time they see it.
Then choose a response that you can actually sustain. An answering service with a real script and access to your calendar. A text back that goes out within minutes and offers a slot. A scheduler on the site for the hours nobody is covering. All three, if the volume justifies it.
Do not advertise after-hours availability until the coverage is real. In this market it is a credible differentiator, and a broken promise on it is worse than never making it.
