Sites near Lido di Jesolo (for Venice)

Kenf

Three couples with caravans are planning a European tour next July/August to take in Venice. My wife and I stayed at Scarpiland campsite last June for a few nights but it seems sites will only accept a minimum booking of seven nights during August. Does
anyone know of a pleasant site along the stretch Lido di Jesolo/Punto Sabbione (for access to Venice) that will accept bookings for four nights during August? 

Thanks, Ken.
