I guess it depends on the 2 year old, i have a very placid and thoughtful almost 2 year old and people always comment on how calm he is. He will sit with me if i ask him to (quietly) and follows instructions really well. Sure he is passionate when he wants to do something but overall very easy to be around - i can take him pretty much anywhere without issues (ie, he doesn't run away, doesn't touch things if i tell him not to etc).

But that being said, we would have someone there who's role is to take care of him and his needs, so i think if it became appropriate we would just have him leave the room. So i guess we'll just have to play it by ear?
