From reading the boards over the past few days looks like the AKL standard view rooms are mostly located above the lobby area and in the front wings of the bldg. (Ostrich and Giraffe Trails).
Unfortunately you will not see animals from your room, most of the standard views face the parking lot or other parts of the bldg, possibly rooftops, etc.
There is a bus that runs to MK from AK but I do know it's about a 15-20 min ride, however it is a dedicated bus and isn't shared with other resorts. If you want to drive that's fine too although half the fun of staying on WDW property is not having to drive unless you're going to another resort in the evening, then it gets more challenging to take WDW transportation as you have to transfer buses.
We are staying at AKL for the first time in May but have visited the resort many times and it is very unique. There are many viewing areas to see the animals from different areas of the resort.
If you plan to spend most of your time at MK you may consider staying at WL as it is a little more convenient to get to MK from there. But, if you want the "animal" experience then AKL may just be a nice experience.
