Besides the drive thru lights is there other things to do that isn’t for small children. My youngest is 15.

I'd say if the lights and some food and very light shopping aren't what the 15 year old likes, don't take them. Girls usually like this stuff, boys, not so much.

There are a few small carnival rides, photos with Santa, and a few craft booths. Kettle corn, and some minor concessions available, such as corn dogs, hot dogs, pretzels, hot chocolate, etc. It isn't anything lavish.
