I have used FairyGodmothers in the past. Once I was very disappointed, as the woman fell asleep, but then so weren't my girls. The other times I was very pleased with their work. I will be using one for my upcoming Dec trip one night, as I will be having a adult night out with DH and my friends to PI.
I am going to move this over to the Family board where this topic is discussed often. Good luck.
