Yes, they do have special activities for Halloween. We were there in October and are going back this year.
They had a children's costume contest, an adult costume contest, a pumpkin carving contest, the CM's decorated pumkins and displayed them. We took a picture of one of the CM's and her NEMO pumpkin and our children. I am trying to get my DH to post our picture of the trip. I'll let you know.
Most of the CM's had costumes on. Children could decorate masks in the Community Hall to wear in a Halloween Parade around the pool later in the day.
They had slime relays on the lawn during the day. At night, they closed down the pirate ship so it would dry and turned it into a ghost ship. They had trick or treating at various different places around the resort-our kids loved this. They handed out really nice glow in the dark pumpkin, cat and witch necklaces that were real popular. They also had a DJ by the pool while the snack bar served caramel apples, cotton candy, drinks and pizza. The resort also provided cider and donuts.
They had a fortune teller at the pool at night, also.
We had a blast! There was a large group of high schoolers staying there for the Florida swim and dive finals and we thought this was going to be awful. They were the best. Some of the nicest kids we have ever met. They made the party a lot of fun. Two of the guys dressed up like Santa and Mrs. Claus and had everybody laughing.
We were so sad when we had to leave. Two of the CM's had befriended our children and gave them little Halloween gifts. It was really nice.
I think we ended the night in the Green Cabin room playing a game of Checkers.
