Booking calendar widget

I saw the fullcalendar from jquery port to meteor but any chance that there is widge somewhere out there that is about hotel booking or any booking for that matter. I looked through github, atmosphere, and lastly npm which did have something, but didn’t come with any documentation which scared me away.

Don’t know how php works, but hopefully all of the events are on the widget side right: https://wordpress.org/plugins/booking/?
