I don't know if they still exist either, but I remember their jingle - the Club Med vacation, the antidote for civilization... (I have this idiot-savant syndrome of remembering jingles from my childhood. Put a Tic-Tac in your mouth and get a bang out of life! Bubble Bubble Yum is so much fun fun fun, it's number one one one in bubble gum... It's a curse. But I can do most the Schoolhouse Rock jingles too, so it's not all bad.)
I've never been able to afford vacations like that, but I do think that Club Med was the grandfather of the all.
