Agree with PP above, max 4.
And, there's no wiggle room there. I showed up with appropriate reservations (lounge for 3 and 2) for our family of 5 and offered, at check-in, to just take one four-top since our kids are small. They said it was a fire code thing and they absolutely cannot seat more than 4 at those tables. They gave us our tables next to each other.
