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.

Did you ever resolve this? I am implementing using HotelRunner now and would like any tips you have found helpful.

I had some trouble with solving this. The support is not as quick as I expected. But the issues are solved. Pay attention by doing the bulk uploads for the accommodations. Be sure to do the right things and reread the instructions several times!
