Whether or not you're a fan of Sex and the City - TV series and movies - there's no denying Carrie, Samantha, Charlotte and Miranda touched a nerve with women everywhere about the importance of female friendship. It's probably one of women's greatest strengths that they allow themselves to 'share' with other women and so build the emotional bonds that carry them through life's challenges - however big or small.

With that in mind, you have a huge opportunity in offering spa events that celebrate women and the joy of friendship.Girls' night (or day) out events provide another revenue generating opportunity - much like the mobile spas we blogged about last week - and help strengthen loyalty among your female clientele.

Why not start with a Sex and the City ladies night out? The evening can include manicures, pedicures using BIOTONE's Marine Therapy Pedi-Scrub and Marine Therapy Pedi-Balm, both with Rejuvenating Complex, facials with BIOTONE Facial Therapy with Bio-Firming Complex MicroRefiner and Massage Creme, reflexology and even hot stone, scalp treatments.

You can customize treatments based on personal preferences. Highlight the event with wine, hot and cold appetizers and even play some of the most popular Sex and the City episodes or one of the movies. You might even want to run a Sex and the City trivia quiz with a coupon for a free or discounted treatment for the winners.

There are an endless number of events you can offer to help women celebrate friendship - birthdays, bachelorette parties, baby showers, moving or bon voyage. Once you start marketing your spa as a venue for women to get together for some good old fashioned bonding, the ideas will start flowing.

Maybe you already are promoting ladies days at your spa? If so, we would love to hear about it!
