Deze plugin heeft 3 blokken.

For a complete setup guide take a look at:

  1. Install and activate the plugin through your WordPress admin.
  2. Check the settings on the “Advanced Booking Calendar” settings page.
  3. Create calendars, rooms and seasons.
  4. Add shortcodes and widget.


This plugin uses four different shortcodes you can put on your pages. We recommend to use one page for each shortcode.

  • Calendar Overview / [abc-overview]
    The shortcode [abc-overview] shows all calendars and there availabilities by month.
  • Single Calendar / [abc-single calendar=X]
    The shortcode [abc-single calendar=X] needs a calendar id instead of X. You can find the ids on your calendar settings page. Example [abc-single calendar=1]
  • Booking form / [abc-bookingform]
    The booking form fulfils two tasks: finding the right room for users and generating booking requests. Every user action happens onpage via AJAX, so the page does not reload during interactions. We recommend to enter the shortcode [abc-bookingform] on a single page.


You can also use an availability check widget. Just go to “Appearance / Widgets” and add the widget.

Die Software wäre Super, wenn die Preisberechnung richtig wäre. 'Das Plugin berechnet Sonderpreise und Anzahl Tage richtig, versagt jedoch bei der Berechnung der Anzahl Personen. Blöd bei Doppelzimmern. Ich wäre durchaus interessiert an der Pro Version, doch wenn Grundfunktionen nicht funktionieren und der Support nichts von sich hören lässt...

Leider bekommen ich das Plugin ans Laufen in FSE. Ich kann das den [abc-bookingform] auf der Seite platzieren, allerdings kann ich nach Auswahl des Start- und Enddatums und der Personenzahl, funktioniert der "Verfügbarkeitprüfen" button nicht

Been using this plugin (free version, which addresses all our needs) for a cottage rentals business. In use for about 2 years so far. Only compliments thus far. Fast support from the developer.

Ich bin eigentlich seit ewig Joomla User. Habe ein einfaches Bookingsystem für ein einzelnes Objekt gesucht. So kam ich zu WP und diesem Plugin. Super einfach, schnell installiert und macht nur genau das was ich benötige, nicht mehr und nicht weniger.Das einzige was mir fehlt ist ein fixer Check in Tag. Das wäre schön zu haben, aber es geht auch ohne. Funktioniert prima mit dem Holiday Cottage! ____ I have actually been a Joomla user forever. I was looking for a simple booking system for a single object. So I came to WP and this plugin. Super simple, fast installed and does only exactly what I need, no more and no less, the only thing I am missing is a fixed check in day. That would be nice to have, but it also works without. Works great with the Holiday Cottage! klaus

The plugin is great and self-explanatory. I am really disappointed with the support. They offer a good plugin for the hotel business, but then leave the buyer alone with the problems. Only answer: can not be done, does not exist .... we do not solve. It was about the booking form, which is displayed in the Theme Hotel Hamburg. The theme itself is out of the question for us. Actually I had decided because of the good reviews here for the purchase version.
