Pretty sure you want to enter 6, but would second the recommendation above to consider a room, even if you just pay for it and never go into it. 1 room at Royal Pacific might be (depending on dates) $400 and that gets you ep for 3 of you for 2 days (checkin and checkout). While ep for 3 people for 2 days starts around $600 and can go up consideably (again depending on dates).
