I think generally it comes down to hospital protocol, doesn't it ??

I'm pretty sure when I had Joel it was only 2 people, with Brandon, he was born in a birthing centre so as many as I wanted. Noah was a c section so only Mark and Tehya, well we had a party there

Perhaps you could call the hospital and ask them Sarah, that way you have some foresight, also if they don't allow extra people you can set about getting it sorted so you can ...
