Piscinas Picornell Barcelona - Nudista Family?

Hi

Are the saturday and Sunday naturist sessions moslty for adults, or is
it suitable for families - do families attend?

Howmany people arepresenton the Saturday and Sunday sessions?

Is there any gay sex practiced during these sessions?

If we arrive before the naturist session (and pay the higher fee), can
we stay for the naturist session or do we have to leave / pay again?

Thanks
