Thank you everyone for your quick response
I booked a dedicated 2 bedroom Savannah view. There will be 5 adults and 4 kids, thankfully all under 9. I think I will give the main bedroom with the king bed to the DIL with her 2 kids. I will give my mom and my son a queen size bed and take the other queen bed with my other son. My mom's friend I will put in the pull-out and I am thinking of bringing my aero mattress so my friend can sleep on it. Would that work

If my mom tried to invite extra people on a trip that I had booked using my points, I think I'd politely let her know that, if her friends want to come, they would have to make their own arrangements. I don't want to sound mean, but it seems to me kind of rude for a guest of mine -- even if she is my mom -- to invite other guests!
I kinda have no choice. She babysits my kids when I am working and she loves a big party, the more the better....
Just because the propect of having both my boys in the same bed as me is pretty unthinkable
This way, I might, get some sleep...Still have to work out the logistics. But I think it might work out at the end. BTW, if we decide to use the dining plan, would MS say no to the extra person?
