title: PHP MySQL Half-day room reservation
body: <p>I'm currently building a web application to book a meeting room. There is no problem on building daily based booking. Now I would like to book a meeting room for half day. </p>
  
  <p>This means I cannot use the datepicker like hotel booking system (the datepicker shows available date and grey out unavailable ones).</p>
  
  <p>I really appreciate if anyone can give me some ideas on how to check the availability of the meeting room. Let's say a person reserved it for morning session. So others can reserve the evening session.  </p>
  
  <p>Do you have any idea on the process flow? Thank you</p>
