T here are about a dozen spas and hundreds of hot springs throughout Mexico, and the following are among the best. It is also the only spiritual retreat of the group.
Mexican spas are considerably more laid-back than their European or American counterparts.
This is both a plus and a minus. You certainly won't miss the towel Nazis common in European spas. These are women who make dadgummed sure that you don't put your bare feet or any other bare part of your anatomy down in the steam rooms and other common areas. You also won't have an exercise dominatrix forcing you to do more calisthenics than you like. One woman complained to me that she missed being together with a group that took classes and exercises together and bonded.
