Are you booking a studio, 1BR or 2BR?
How many days are you planning on staying?
How many in your party?
We recently took a 5-night stay to AKV and stayed in value rooms. Originally, we were planning on a Su-We stay in a value 1BR. Then, great airfare came out and I added Saturday on in a value studio. There are only 4 of us, 2 adults and 2 young kids (ages 3 and 5) so we had a few options.
The studio we were in had a great view of the sunset savanna. It was noticably smaller than the savanna studio I stayed in last October, but it was perfect for the one night. I liked the room very much, but I will say that any more than one or two nights with the four of us would have felt quite cramped.
The value 1BR was on the same wing, a few doors down, also with a great savanna view. This room was PERFECT for our family. Yes, it is smaller than the standard/savanna rooms, but it still had everything we needed. We never felt cramped and there was plenty of room for our luggage, strollers and sofa cushions!
After this stay, I can honestly say that I am glad that we own at AKV. I think those value rooms with the savanna view are going to become Disney's new "best kept secret". We got a great savanna view for 28 points less than booking a guaranteed savanna view! With 40% of the value rooms facing the savanna (and another 40% facing the pool) it is a gamble I am willing to take.
The only "negative" thing I have to say about the value rooms is that they are only available in Jambo. This makes our decisions more difficult. We have such a small contract that a savanna view (at Kidani) will allow us to only vacation every 2 years. If we book value (at Jambo), we can go two out of three, or more if we stay in studios.
Good Luck!
