I thought that seeing the animals was a "ho-hum" experience, I wouldn't pay extra for the savannah view. A pool view however, was great at $140 per night. You can't find this room for 14 points per night, so rent those points!! We rented our points to stay concierge for Friday-Saturday nights, on an AP the room cost us $416 including tax and extra cost for two kids over 18. It was definitely worth it to us for two nights, we wanted to do the sunrise safari and you can only do that on concierge level. The sunrise safari runs about $50 per adult, the sunset safari runs $150, and you can only do them twice a week, Tuesday and Saturday, I think.
I wouldn't do concierge longer than two days, because in order to get your money's worth, you need to stay at the resort. The concierge level schedule is: 8-10 am coffee, juice, pastries, fruit. 11-2 snacks like cheese and crackers, cold fish, tiny sandwiches, etc. 2-4 they added stuff, I think. 4-6 were oerdurves, 6-8 were desserts, and after 8 are evening cordials. We had a great time eating

You have to get there at the beginning time because once the food is gone, it's not refilled. We never ate anywhere else while on concierge, and several people just sat up there all day

At the beginning time you have a nice selection of 8-12 items, but it goes fast, which explains why some people here had very different experiences on concierge. Going at each of the times helps for the staff to get to know you, so you can get tons of other stuff--no beer?? Ask for some, it's in back. I'd like water for the pool--out comes 4 bottles. I learned to like Bailey's and coffee while at concierge
Buy an AP, it's only about $300 with the
DVC discount, and it is so worthwhile at AKL. You will make your money back right away if you are planning to stay anywhere besides at a DVC resort. And rent out those points, unless you can get concierge for 43 points(you can't).
