We attened the Halloween Party in October last year and I dressed up, along with my 2 DDS. I didnt dress my DS, because the costume I brought from home was a one piece, sweatshirt material, Tigger costume and it was REALLY hot that day and night. I dressed in a poodle skirt outfit, my older DD wore a 50's girl outfit too, my younger DD was CInderella, and my DS and my parents wore orange shirts with pumpkin faces on them. My mom made those before we went. I would say most people were either dressed up in costumes, or had halloween shirts on. Just watch what you bring with the weather.. it was really hot and humid when we were there. It was still really hot and sticky at night. We did bring our costumes from home and we all just wore our sneakers. We had fun at the party! We are going back to the Christmas party again this year!
