Enquiries Page Calendar Doesn't show Availability

On enquiries page I noticed the calendar doesn't display the booked periods. It only gives you a message saying the period is booked after you select it.   It will be annoying for people if the booked periods aren't shown and they have to keep guessing them!  What benefit is there in showing a calendar that doesn't show booked periods?  

I have been told by support that the guests are expected to check the availability calendar first on another page.  In reality people may be emailing lots of accommodation and may not have the time to check every page.  Can you not make the calendar the same as the book now one?

I would ideally like the Book Now button to give you the option to choose Enquire now if you preferred so it woudl do both jobs with a notes section.
