AKL. It is a great resort, lots of activities, is a bit remote from the theme parks (good, IMO, if you aren't going into the parks) and has fantastic dining options. Also, you can use either of two great pools! Finally, there are the animals to watch either from your balcony or one of the very nice viewing areas. There is an evening tour of the savanna at the resort that you can take part in (for a fee) with night time viewing goggles. It is fun and informative.
I would find it difficult to stay in a MK area resort and not go into the MK. But that is me. YMMV.
Enjoy wherever you choose!!! all three resorts are special in their own way.
