First don't panic. You will be fine. I would pick her up as much as possible so she is out of reach of small small children who may be more impulsive than adults and often just want to pat the pup on the head. When a person shows interest in her ask them to help socialize her. People mostly love to be helpful. Give them some small (really small) yummy treats to give her. Have them talk to her while she takes and eats the treats. If she decides she doesn't want to eat them she is telling you she is nervous and just say thank you and stop while you are still ahead. If she is enthusiastic for the treats then ask them to gently pet her on the shoulder or on her neck, not on the top of her head. Keep going as long as she is taking treats. I think poodles bear a lot of rough petting since so many people want to stick fingers into the curls. When my nieces were small the big sister always used to run her fingers through little sister's hair. Little sister hated that and one of the very first things she said reliably was "make her leave my hair alone!!!"
