I'm going to insert the caveat here.
If you are worried about it because you are afraid you won't fit in with the other families, and you know you like character meals, then don't worry about it and go.
If you are worried that it will be loud and chaotic, it will be. If you are asking because you would not be comfortable with loud and chaotic and with children running everywhere, OR if you are going there primarily because you are interested in the food and not the characters, then I probably would suggest that you try another restaurant.
