Hello, Mariah,
I have just returned from WDW where part of our stay was at
Bay Lake Tower, which hands-down won my family over as a favorite resort. We loved the sleek, modern decor and its proximity to the Magic Kingdom (you can walk to the park!). The villas are also connected to the Contemporary Resort through a walkway, so you can easily visit the Contemporary Resort and catch the monorail. It seemed to have all the magic touches about it to make it special for us.
In sharp contrast, Disney's Animal Kingdom Lodge Villas at
Jambo House and at
Kidani Village are breath-taking as they capture the spirit of Africa. And with savannah view rooms, you can experience the joy of having zebras and giraffes right outside your balcony. But don't worry if you don't have that view since there are plenty of lookouts throughout the resort for all guest to enjoy the animals. I truly believe this resort to be a unique experience; but I should caution you that while it is right next door to Disney's Animal Kingdom, it is farther away from the other parks.
Truly, I wouldn't hesitate to stay at either resort; they are both favorites with my family that I hope your family would enjoy just as much.
