Affordable/minimal effort idea: collingswood. The lights look nice and they have a bunch of things to do throughout the next month, like free visits with santa

Or Dec 3rd, family night will have activities for the little ones and a fireside showing of frozen 2

If you want to make it a little less affordable, you could have brunch with the grinch. But you could also stop by for a treat after visiting with Santa and looking at free light displays. If you walk to the end of the shops, next to the one church there is a house with an insane amount of decorations. I feel like at 2.5 years old that would be as impactful as paying for a light show.

If you end up going to peddlers village, check out their calendar too. I think they do a parade?
