I think it comes down to location. If you want to be in the thick of things, you can't beat the Epcot resort corridor. Walk or boat to Epcot or Studios, tons of dining options at all those hotels and the two parks all right there together. I was just at AKL Kidani for a week and I absolutely noticed the length of those bus rides. AKL is a good distance from Epcot and MK; if you're spending the bulk of your time at those two parks, you will notice how much time you spend in transit -- especially if it's the end of a day and you're standing up on that bus!!!

That said, you can't beat AKL for ambience. Protip -- Kidani's pool is actually more fun for the kiddos, with a splash park area and a better slide (according to my god-daughter and her sisters).
