Co-Ed Bridal Bachelorette Party

My friend is getting married and left me in charge of the bridal shower and bachelorette party. She claims she does not want to have men at her bridal shower, but she wants to have her husband-to-be and his friends at the bachelorette party. .She doesnt want any drinking or strippers. She just wants everybody at the event to mingle and have fun. I told her that she should have a co-ed bridal shower and let all her girlfriends be at her bachelorette party. She is adamant about an all female bridal shower. How do I propose the idea to her without taking away what she wants for her wedding. Also, to save money, how do i do both and include everybody.
