The Villa is gorgeous, the hostess is gorgeous....Big But!
Rather than focusing on the infantile drama of the staff....which is a HUGE TURNOFF, The FOCUS should be on the guest's, how the food is prepared, the beautiful table settings, how the flowers are arranged. How you go about choosing your guest's. Perhaps some history of the Villa.
Forget the staff, they will be the ruin of your lovely program.
Wishing you good luck!
