We have stayed at AKL at least once a year for a week, every year, for almost 10 years. The buses are the buses property wide, I think that on average they are very good, but there are times that you can have longer waits. Overall, I have had no significant issues with bus service at AKL, and certainly don't think it is any worse than any of the other resorts we have stayed at (deluxe, moderate, and value). We still use WDW transportation the vast majority of the time, with an occasional Uber thrown in there, and are satisfied with the service. That said, it is all about timing, if I get to the bus right before it pulls up I will feel like I had great service, if you come a minute after me after the bus has left and have to wait for the next one, you may complain about long waits. Also, there are some people that are just not bus people, we have traveled with them, and even though I thought that waits were short, and service efficient, they complained about long waits and inefficiencies.
