WP booking system is an interesting add-on for several reasons. The first one is its price which is really affordable… starting at $49 (par an). The second is that it can turn your website into a simple, but very efficient booking tool, with a calendar that can be synchronized with your favorite OTAs, forms, and payment system.
On the other hand, there is no channel manager at wpbookingsystem, if you have many OTAs, you will have to adjust your prices manually. But is this really important?
