Idea's for a Spa Retreat and Eat Party?

My friends own an up and coming, successful Mobile Spa Party Unit. She is planning on hosting a His and Her's party. Its going to be held in December, and there is going to be a His Party, and a Hers Party. Of course Spa themed, but we are looking at what kind of vendors should she invite to the advent. She currently has chefs, and party planners signed up for the event. Any ideas what you would like to see. I was going to contribute products from my business in gift baskets as a raffle for the event.
