HotelRunner experience

Is there anyone with experience using HotelRunner who would be willing to share their insights with me?
I have a client for whom I implemented HotelRunner in Wix. The website is www.surfcamp-veluvemeer.de. I’ve had to deal with some issues regarding double bookings and would like to exchange experiences with you to solve problems and find solutions.
