AKV standard or savanna view? I’m not quite as old as your mom but I am one who can spend significant time sitting on the balcony drinking coffee or wine and watching animals (DH almost has to drag me away to the parks). OKW has lovely views too, but not as unique - golf course and woods. AKV Kidani will have 3 full bathrooms while OKW has only two, but OTOH OKW has 2 queen beds in 2nd bedroom while AKV has one queen plus a sleeper sofa. For dining AKL has Jiko, Boma & Sanaa, OKW has Olivia’s.
My personal preference would be AKL Kidani, savanna view.
