Personally, I love AKL, and so does my family. There is nothing like looking out there and seeing all of those animals, and of course walking into the lobby is an experience all in itself. We do not find the rooms small or dark by any means.
There is one small thing I do not like about it, and that is the food court -- The Mara.
I suppose I am just picky, but I burn out on it after the first visit. I know Boma and Jinko are there, but we have a 7 year old who is a picky eater. It's not bad , I mean I have obviously eaten there and it's been okay , but I personally just do not care for it. I know most people say there is such a variety there, but I must be wearing blinders when I go in there, because I just do not see enough to appreciate it. DD likes it also because of the cartoons showing in the dining room. The dining room by the way, reminds me of an elementary school cafeteria, which I think does not help my view of it. I know, we could go outside, though, and sometimes we do, which helps.
Anyway, like I said, I understand this is likely unique to me and my own "issues", lol.
