Disney will not let you have more people on the reservation than the room will legally accommodate. All registered guests will get a wrist band.hmmmm there is another post about maximum room capacity
You can have 4 people registered plus one infant that is under 2 or 3 years old for a hotel studio.If I have 3 children, my wife and I in a hotelroom. Can we have 5 wrist bands for the pool?
