FWIW, CSR is pretty centrally located. We never found the buses to anywhere to be a particularly long commute. Its one of the few resorts where not having alternate transportation doesn't bother me.
I'll play devil's advocate and respectfully disagree. In our experience staying at AOA, we absolutely thought the Skyliner was a game changer. Granted, this was before covid so I can't speak to how its going now. Last Fall, we also found what appeared to be long lines at the CBR hub, but the difference between a long line at the Skyliner and a long line at a boat/monorail/bus is that the Skyliner's lines are continuously moving. They load one party after another so even if I'm 20-30 parties deep in line, it took less than 10 minutes to get inside a gondola. Now, with limited operating hours, staff, etc. I could see it taking longer. It would also take longer if there is inclement weather or something requiring a stoppage. But otherwise, the main benefit of the Skyliner is the efficiency of the continuously moving lines and we thought this was very apparent and as fast as expected.
