Yes they will put them together and you can all watch (though depending on where they are seated and how many other kids brought 2 adults, it might be a bit crowded). Last time we were there they put my 2 girls in a room in back with 4 seats and then brought in another pair of sisters for the other 2 seats. It was really fun.
You’ll have to figure which child to watch. The 3rd adult won’t have the best choice if this is how the policy works.
When they say "Two adults per child" where do siblings count in there? When our DGDs went to BBB several years ago, there was no such policy. Hopefully, this is just to eliminate one child being watched by parents, grandparents, aunts and uncles. I hope siblings are unlimited.
How many siblings? I believe the rule is due to limited space and the website actually specifies "2 guests" and not "2 adults." That said, I'm sure they'll try to accommodate as well as possible if it's 1 parent and a couple of siblings.
Do what I did. Grab what time you can get and keep looking for cancellations. When we went in June, I found they were dropping all kinds of reservations a week or so out. You could choose your time. I haven't checked since then. When we went the time before last, I had to book 4 girls into a morning slot. I was able to at 5 days out, and that was 4! You should be able to get something. It also doesn't hurt to call, either. My granddaughter wanted to do a little later - after we rode Tiana. She didn't want to get wet. I think we had 11:45. Most of the time. we get early, then head to Cinderella's Castle for breakfast.
When we took our little one this past time, her older sister went with us. I was going to sit on the side in order to not take anyone's space, and they asked me if I wanted to sit in front of her. There was space, and it was comfortable.
