Hi ya zuzu310, I can understand how you might feel about having a child dumped in your lap, especially if not asked beforehand.

However many of my favorite moments at DW have been with a lapful of newly met children in my lap.

I love it when a family who has been trying to get in every attraction comes by and I am able to share a bit of the magic with them. Not the rude obnoxious ones though. Even I am not THAT nice.
On our last trip we were at the train station and met a family with 5 children and I ended up draping my jacket over two in the stroller while two of the girls sat on my lap. I have a large jacket and a large lap.

They were very nice people and one of my favorite memories.
Karnac, the children can crouch down under the table and they do not hurt the view at all. I do that often.
That being said I CAN feel you pain in suffering for a good spot only to have someone else spoil it for you at the last minute. I have had that happen also.
Naw. You misunderstood me. I didn't say that the children blocked my view at all. I just noted that the CMs asked the children to remain at their tables. (I didn't ask them to in any way.) As for crouching down under a table, if one did that, one would not be able to see anything. Not a drop of the parade.
