Looks like you got a lot of good ideas already but there is also a Christmas Village up past Scranton that has it looking like the North Pole and it is all snow covered and looking just like the North Pole with real reindeer and all kids and parents just love it. Also in New Jersey on the Black Horse Pike (rt 42 then goes into rt 322) they have an amusement park called Story Brook Castle and they have it all decorated for Christmas with Santa and a reindeer barn. They also have a little chalet with Santa's bed and fireplace. You can take pictures and they have hot chocolate for the kids. Up in Langhorne there is a park with festival of lights and you drive through the park with all kinds of light decorations like elves and so forth and this is FREE
Re: Fun Holiday Outings????
Wannamaker's (aka dowtown Macy's) has a great Santa as well as an organ and light display that's really special.
Polar Express in Straudsburg, PA or West Chester, something like that
