Wagon or Carriage?

We’ll be visiting at Christmas time again this year and want to tour the campground, of course! (what a weird thing to say anyplace, but Disney) I’d like to do the wagon ride since it’s much cheaper than a carriage, but the wagon is walk-up only whereas the carriage can be reserved at 180 days. We’re planning on Monday 12/18 that has a resort CL of 7. We’ll attend the campfire, but leave before the movie to tour the grounds. Anyone have any experience with the wagon rides and crowds. Do the wagon rides fill up? Do they run extra wagons when the crowds are high? Will the wagon route allow us to see a good portion of the campground decor?
Thanks all!
