Hi Jane,
You must be so excited about your trip - October will be here before you know it!
Disney's Animal Kingdom Lodge is a beautiful, unique place to stay.
In a Standard Room you will find two queen-size beds (or one king-size bed) and one day bed.
There are also some Standard Rooms with Bunk Beds but these are slightly more expensive and I would imagine that it would have stated a Standard Room with Bunk Beds when you made your booking if you had selected one of these rooms.
As there are five guests in total staying in your room, you will be allocated a room with two queen-size beds and one day bed. So, one of your children will be able to sleep on the day bed whilst the other two share one of the queen-size beds.
Please do not hesitate to visit us again should you have any other questions.
Wishing you a magical holiday, filled with memories which will last a lifetime!
