Hi Annie,
There is some information about babysitting and child services on the Amenities & Services section of the Animal Kingdom Lodge Resort page on the Walt Disney World website which you can find
HERE.
You have two options available:-
1/ Simba's
Cubhouse which is located on the first floor near the Uzima pool deck area. This is a supervised activity center for children ages 3-12 that is
open daily from 4:30 p.m. to midnight. Children are able to play videogames, enjoy dinner and snacks,
watch Disney movies and interact with other kids their age, while
parents are off experiencing more adult-oriented fare.
2/ Kids Nite Out an independent childcare provider available at Disney's
Animal Kingdom Lodge offers you the convenience of one-to-one
in-room babysitting, allowing you the flexibility to enjoy your vacation
your way.
To make a reservation for Simba's Cubhouse or in-room babysitting,
please contact Disney's Animal Kingdom Lodge front desk or Concierge
during your visit.
I hope that this information has been of help and that you and your husband manage to enjoy a lovely dinner together during your visit!
