We made 6 exchanges with Homelink over the years, and never had any problem. We never signed any contract up till now, so that's why our past exchanges aren't listed. But here they are : Worcester, England in 2004 ; La Manga, near Carthagena, Spain in 2005 ; Marseille, France in 2007 ; London, England in 2008 ; New York City, USA in 2012 ; Tarragona, Spain in 2013.
This year, we are going near Volterra, Tuscanna, Italy.
