Have a look at Montestigliano in Tuscany. Their biggest villa (http://villapipistrelli.com/english/villa-pipistrelli.html) has its own private pool and is secluded from the rest of the farm estate. There are other smaller villas which share two pools - a quiet one, and a children's one, set amongst the olive groves. Here's a link to their weddings page on their website. http://www.montestigliano.it/site/Weddings. Luisa Donati speaks excellent English and will make sure that all the details of your special day are taken care of. Good luck for your big occasion!
