I’m currently at AKL for resort #2 of a 4 resort split stay. I started with two nights at Pop and I LOVED the Skyliner. I arrived super late Saturday night, so no parks. Sunday, I headed to the Skyliner at 8:30 and hopped right on. I got off at CBR and walked to Riviera (I’m not sure if they would have let me on the Epcot line because it was too early, but I didn’t even ask because I felt like walking). After QS breakfast and soaking up the atmosphere, I lined up at the Skyliner at about 9:45. They started loading about 10 minutes later and the line moved quickly. I left Epcot at about 4 for a room break and there was no line. Around 6, I hopped to HS and again, no line. There was a HUGE line leaving the park just after 8, but it loaded quickly and I only waited maybe 10 minutes. I hadn’t stayed at Pop since 2016 and my least favorite thing was waiting for a bus at HS at park close. With social distancing and limited capacity, I can’t imagine how bad it would have been now. I was super grateful for the Skyliner. Same thing happened the next morning: there was a huge line to board at Pop but it moved very quickly. True, it wasn’t at rope drop, but it was still morning and there were a ton of people heading the same place that I was.
TLDR - the Skyliner was much, much better than the bus.
