For me, the perfect holidays are with my family, with all the components of my family, those what are every day with me, and those what cannot be with me all of the year.
It's a very special time for the families who cannot be together all the year, for many reasons, usually for our job.
My prefered activities, in holidays, are those related with the sea, specially the snorkelling. But, in the Spanish Mediterranean, is very difficult to found the ideal conditions, because the contamination of the coasts, and the changes in the climate are destroying the see floor.
