I don't find the datepicker calendar to be very intuitive because it uses colors to denote dates not available. It does not display a color key to make it clear to people what the various colors represent. Without a key, a person would have to deduce what the colors mean.
On my site I modified the CSS and wrote some jQuery to change how the calendar functions. It now places an "X" on dates that are not available. I believe the "X" is more intuitive and I would like to suggest you consider changing Beds24 to use the "X" for dates not available.
You misunderstood. I am a developer. I have already implemented it on my site. The screen shot is live and working.
I am requesting that you make this a feature of beds24 because, as I explained, your current implementation is confusing to people who are trying to book a room. They don't know that a certain color means a date is not available.
My solution is better and I'm suggesting you adopt it for all of your other customers to be able to use.
