I've had some dealings with them on an unconnected (and much simpler) client matter, and they were absolutely hopeless in dealing with on getting anything custom done. Even simple custom for something a client was paying for.
Hence would be much more pain-free if there was already something existing, so thought I'd ask first.
But one negative they might see from having this would be that it dilutes traffic to their own site, which they would probably like to avoid. But can't hurt to ask...
Any luck with this. Looking at something similar that Airbnb seem to do with a simple iCal style integration that just syncs with there online Calendar. Can't see anything of such document with Stayz unfortunately
Dates are returned in JSON format, which makes for easy integration .
To avoid having to code a calendar myself, I used https://github.com/zabuto/calendar
