BOG pre order question

[wildfortink]

I booked a lunch at BOG for 9 of us. My family, my sister's family and my mom. When we go to pre order our lunch will we be able to go in seperately on our own MDE and order for our own individual parties? Will it allow us to charge our groups seperately for our dining credits? I called Disney Dining and the CM told me it would be charged seperately, but I've heard others say no. TIA.
