I actually was at Pop last week, checked in on September 17th and out on September 21st. On Friday, September 18th we were going to Hollywood Studios and I too had heard about long waits at the Skyliner. As such, we decided to call a Lyft to be safe. We were picked up at Pop around 8:45 and arrived at HS shortly after. There was already a line at the entrance so we had to sit for about 15 minutes or so until they started allowing cars in. Once they started moving vehicles through the check point it was around 9:20 when we were dropped off at the front entrance. We were allowed into the park at that point and were in line for Starbucks at Trolley Car Café at around 9:30. I would say if you want to make sure you don't get held up in the Skyliner line you can call an Uber or Lyft. We did experience the Skyliner the next morning on our way to The Riviera Resort for a breakfast at Topolini's Terrace. We arrived at the Skyliner around 8:45 and were backed up around the 50's section. Again, it looks longer than it is due to spacing for social distancing. We were up to board at around 9:00, so just about 15 minutes. We did have to get off at the hub at Caribbean to then get on the one going to the Riviera, but that wasn't long either. It moves quickly. We did the Lyft on the HS day because we wanted to make sure we had every opportunity to try to get a boarding pass for RoR. Calling a Lyft gave us that opportunity. I will say I did notice that the Skyliner was running earlier on Sunday going to HS. It was already running around 8:30. We are going again in December and are booked at at AoA. I think we will depend on the Skyliner to get us to HS. We will just arrive at the Skyliner early. It's really a great means of transportation! Hope that helps some!
