Best WDW Santa?

[pixiedust33]

We’re going the week before Christmas, likely hitting all four parks at least briefly and trying to decide where to meet Santa. In terms of best, I suppose my first priority is the shortest line. But also interested in who has the best set for pictures or where people have had great interactions! I know he’s at all four parks and Disney Springs but looking for advice on which one to pick. Not really thinking the Epcot storytellers as I want someone my four year old will unequivocally believe is Santa. I’m leaning towards MK, because we have a full day there, but would be swayed away from that if you all tell me it’s much more crowded there.
