Welcome to the Disney Parks Moms Panel, Debra! Thanks for stopping by with your question.
Currently, the only resort of those that you mentioned with the option of a King Bed that will accommodate 3 Adults is
Disney's Port Orleans Resort- Riverside. My family and I have stayed at Disney's Port Orleans Resort- Riverside and loved the laid back, Southern style that you'll find throughout. We also loved the convenient proximity to
Disney Springs.
Hop on a water taxi and you're there!
The room option with a King Bed that sleeps 3 Adults includes a "Child-Size Pull-Down bed." The measurements on this bed are decidedly smaller in both length and width than a regular twin mattress, but I do know adults of a smaller stature that have slept on these comfortably all night. Depending on your third guest's preference, this bed might work out perfectly or you may want to request an air mattress. These are available at the
Front Desk on a first come, first served basis. Keep in mind this availability is not guaranteed.
Debra, I hope this helps as you're sorting out your sleeping arrangements. A good night's rest is important so you can be bright-eyed for park touring the next day.
Thanks for stopping by the Disney Parks Moms Panel. Come back and see us with any other questions you might have,
Lauren
