Can you have 10 people in a cabana at the Cove in Atlantis at the Cains Pool?

We are going to rent a cabana at the Cove and we have 8 people. We may have other friends that stop by from time tot time. I am paying for the cabana, but can you split up the food bill among couples in the cabana or does it all have to go on 1 bill? I would prefer to split it up.
