title: Reservations in Drupal using Date and Calendar modules
body: <p>I want to create a page where users can book a piece of equipment for a certain number of days. </p>
  
  <p>I'm planning to implement that using the <a href="https://www.drupal.org/project/date" rel="nofollow">Date</a> and <a href="https://www.drupal.org/project/calendar" rel="nofollow">Calendar</a> modules, as I'm already using them for other purposes on the same site. Each reservation would be a node, they would be displayed using the calendar view.</p>
  
  <p>I've looked at quite some modules that are already written, but they did not fit my requirements. The <a href="https://www.drupal.org/project/merci" rel="nofollow">MERCI</a> module was too complicated and some parts did not work for me. The <a href="https://www.drupal.org/project/simple_reservation" rel="nofollow">Simple Reservation</a> and Event Bookings modules also did not work reliably for me.</p>
  
  <p>How can I easily prevent that the same day is booked twice?</p>
  
  <p>How can I add a link to each day in the calendar view that creates a new reservation and prefills the date that was clicked on?</p>
  
  <p>How can I disallow reservations that are too far in the future?</p>
