I would have to agree with you on AKL being a bus ride to all the parks and a little bit longer than the other resorts but as long as you're ok with that, then it's not a deal breaker for all. The nice think about AKL is that getting to the bus stop is all covered so it's very convenient in the florida rain storms/heat.
I've stayed at both and for us, the skyliner is really nice and being next door to RIV is great too for extra food choices....and I love that benefit at CBR, but beyond that, I just don't care for this resort mostly due to the buses. Disney buses are sort of their own thing but for us, it's just too many bus stops. I know that there are a ton of people that love it but the large footprint and large amount of bus stops are a negative for us. FYI-- they're doing a soft goods refurb on various buildings, so depending on where you stay at CBR, you may get an older room or a refreshed room. For me, we last stayed over the summer at CBR and when the skyliner goes down, the transition from skyliner to bus service to Epcot/DHS can be slow. If you're timing is bad, like ours apparently always was lol, we ended up sometimes waiting 20 min or 45 min+ for bus service to start when the skyliner went down. Even if a bus was at the skyliner stop, it wasn't for Ep/DHS, it was so crazy. Definitely bus management, but it's still a part of being at CBR in the summer with constant T storms. We bailed on waiting another time at the 35 min mark and grabbed an uber instead. We stayed for 5 nights and by the 3rd night, we were totally over the 8 total bus stops to/from the parks......it's not horrible, just not enjoyable. But when the skyliner is running, it's really nice and very, very convenient. Lobby is very nice and was redone in the last 5 years and the pool is also nice.
AKL overall is a great resort and has good dining options, a fun pool, fun activities and of course the animals. If you have the option of extended hours for deluxe resort guests when you're there, you'd get this staying at AKL so that could be of benefit and you won't have that option at CBR. I know the price difference for resort view vs savanna can be steep but what helps is all the nice look outs around the resort. If your child likes animals a lot, this is a really nice property. Yes, it's a bus ride to all the parks so you just have to take that into account when planning your park days.
