Venice area campsites

dougiec

I am looking for a campsite in the Venice area of Italy who will permit me to stay for only 3 nights in May next year. Obviously I am planning on a visit to Venice itself for at least 2 of these days so I would be looking for a site where I do not need to
travel for a long journey to reach the city from the site using public transport preferably. The trouble I am finding is that the sites I have tried so far are for a minimum of 7 nights. I am not bothered about a pool or some of the other luxury facilities
but would prefer that the toilets and showers are reasonably clean. I doubt very much if I am going to get caravan club site standards but one never knows! Any suggestions or recommendations would be gratefully accepted.
