Like many a CEO, Terry Montesi of the Trademark Property Company owns a second home-and could easily have others. But even as it is, he and his family get to visit their country place in Possum's Kingdom, Texas, only three times in a year, at most. To Montesi, unhappy with the too-high maintenance and waste, a residence club called Solstice offered the best solution. It would give him access to 10 other second homes, minus the responsibility, maintenance and, yes, guilt over not making full use of his home. Since joining Solstice a year and a half ago, Montesi and his family have enjoyed stays in the Napa Valley, Telluride, Cabo San Lucas and Aspen; on top of that, they enjoyed a getaway on a Solstice yacht to Paradise Island, in the Bahamas.
