My wife typically goes on a girl trip once a year or so. However, it is usually with one or at the most two other women with whom she has had a long friendship, and they are also married! They typically do the fun and sun thing and just relax with no kids or husbands. I would blow a gasket if I found out she had danced/ interacted with other men on these trips. I could care less about them going out for a drink together. Just another form of relaxation and very easy to hang a "NOT INTERESTED" sign.
Do you travel on business? Would your wife be comfortable with you hanging out at the singles bars or crusing the red light district with your friends to see if they could score?
One of my tests about acceptability of behavior is to try the shoe on the other foot and see how well it fits.
