Our family is planning on meeting somewhere the week between Christmas and New Years. We definately need an indoor pool. 1/2 family is in Baltimore the other 1/2 is in upstate NY so we figured a resort in Pa would work well. I have checked out Willow Valley and Great Wolf Lodge. Anyone have any opinions on these or others? Would be good to be somewhere with other kids activities. The kids range from 14 to 9 including one autistic child.
