Really for 1 night it wouldn't be a big difference...
Major differences are:
Jambo: Larger Pool & area around it, smaller slide.
Quick service restaurant---> Mara
Huge main atrium / lobby.
(2) TS restaurants.
Lounge area.
Main store near lobby is a lot bigger
2nd stop to get on buses for parks, 1st stop for DTD.
Kidani: Smaller pool area, with longer slide, and smaller kids water play area.
No quick service, but coffee & drink refill spot in store. in the lobby.
(1) TS restaurant.
Smaller Lobby.
1st stop to get on buses for all parks, 2nd for DTD.
I'm sure there are more that I'm missing but you get the gist of it..
