We were upgraded to the Portofino Suite last summer. It is a parlor attached to either a King Room, or a Queen Room or both. So, I guess you could have 4 in the Queen Room and another 2 on the pull out in the parlor area. There is a full bath in the parlor area so it isn't too bad.
We actually had both the King and Queen Rooms and there were 7 of us total.
