I'm amazed that the visitor parking is not busy - it's incredibly difficult to get a spot in the village and a lot worse since the island/weir were built.
In the complex I live in it is people who have two cars and abuse the spots claim that it's easy to get a visitors spot. However, when I've visitors, it's not so easy!
Parking in the village is likely to get worse when the road works are finished in the village. I believe that there will be paid and display parking. In addition, there will be far fewer spots available. If you count the number of properties, without off street parking (I'm not including apt's here - they "should" all have sufficient in their grounds), versus the number of spots, there is a large discrepancy.
However, if the visitor parking is under utilised in your complex, absolutely do what you can to improve it as it would help the village. Your management company should be able to get the data from NCPS, I'm pretty sure that we got it for our complex.
