I think that this happens because of him saving Arthur's life on the very first episode. Maybe it's one of his privileges being present at all the important events in Camelot. It was the same with Gwen, though. In celebrations, there are other servants who are pretty busy serving the king or the knights and that's why they aren't seen at all. Merlin and Gwen only have to serve Arthur and Morgana respectively, so that's why they have their "free time" to enjoy the celebrations themselves.
