When me and my friends hear the word "retreat"  we don't think of places where we can go for some peace and quiet, i.e. a couple of private Villas in Italy.  Instead we picture tables and tables of chocolate bon-bons, cheesecakes, banana creme pies or ice cream sandwiches that we are required to eat over and over again.  I don't know about you but I like my definition of "retreat" better than Merriam-Webster's Dictionary.
