We have only stayed there once, and yes it was savanah view. To us, seeing the animals was the main reason we chose that resort.
We did enjoy our coffees on the patio each morning, and if you don't mind getting dressed and walking down the hall to a public viewing veranda, than you don't need to get a sv. The public areas are lovely, of course.
The animals feeding areas are in the savannah, so they are always out there, since that is where they will get their food. Disney did this purposefully, so that guests would always see animals.
If you can swing a sv room, I would do it. If not, don't forgo AKL by any means, get the standard or pool view. It is a magnificant resort.
And it might be 10 min or so farther than other resorts, but in the grand scheme of things- so what?
