This is - hands down - the most intuitive, easy, understandable, efficient and thought-through plugin I ever stumbled across. What is even more surprising, is the support from the developers. Whenever I had a problem, they reacted literally within minutes. For instance, I stumbled across a minor problem provoked by a third party addon "polylang", which of course has nothing to do with the booking plugin. Guess what, they downloaded the third-party addon, tested and removed the problem in the next update. Kudos.
