estivate

"I suppose I passed my youth in the amateur fashion common to certain youths born to a gracious life, to the luxury, calm, and voluptuousness of my generation—never mind which precisely—of European bourgeoisie who estivated on the North Sea or Atlantic coast rather than the Mediterranean or by placid Alpine lakes rather than along the lagoons and grand hotels of Venice."
-Tintin in the New World by Frederic Tuten, p 135
