Dear Elisa,
My experience has been quite good actually. I managed to get 4 families booked so far, however, I would like to increase my conversion ratio of views to booking further.
I believe that 'Presentation' plays (site pictures, description of the amenities and its proximity to nearby areas of interest) an important role in converting customers, along-with providing unique add on. In my case I have paired a session of astronomy, where I get to observe a few celestial objects such as Jupiter with its 4 moons, Saturn with its rings & the Moon's impact craters through my in-house telescope. This definitely gives them a memory to cherish and remember, as also helps in targeting families having kids, who might be more into this stuff. Also having my listing competitively priced (using dynamic pricing, still fiddling around with it) definitely helps.
Best Regards
