We just arrived home last night from our first AKV stay too. We stayed on the concierge level for the first 7 nights and then a regular savanah view the last night.
We loved the club level!! We had a savanah view and could see the new building in the distance. We had an eland right outside our balcony all the time, we named him Eddie. We also saw giraffe, ostrich, zebra, and various birds.
Our regular savanah view room was not the greatest at all but it was only for one night and we did see red river hogs, wildabeasts, ankole cattle and lots of different kinds of birds.
We had a car so we only used the buses twice. Once to go to and from DTD, those were OK. On our Epcot day we had gotten there early and had a front row seat. We wanted to go back to the hotel for a break and decided to leave the car and take the bus back since we were planning to come back for Illuminations. We waited 30min for a bus to leave Epcot and then 25min at AK for a return bus. Confirmed for us that we prefer having a car.
We really loved our stay there.
