When the skyliner is up and running, it's a big benefit over buses for sure, esp if you have a stroller. It's a great perk. Where it can become troublesome is inclement weather and buses come back online to take you to Epcot/DHS. They transition from skyliner down to then wait on a bus can be lengthy. If you're going in the summer/rainy season, it's definitely a consideration. We never had any major problems during an August visit since we had no ADRs or anything to rush to the parks for, but we had some long waits for sure. We also encountered people who had ADRs at the park and were late. Sometimes it was 30-45 min and other times it wasn't near as long but as always, it's all about timing. If you come in mid storm, the buses might be rolling already but if you roll into the skyliner station and a storm rolls in, you're going to wait a little bit for a bus.
AKL is nice but it's not near any park except AK and every park is a bus ride away. I would stick with either CBR or POP if you're trying to avoid a lot of buses. If you stay at CBR, request Jamaica as it's near the skyliner and not too far from the lobby.
