We were at Pop last week and used Skyliner several mornings. We found that getting in line around 6:30 am put us fairly near the front (on the bridge one day and just off the bridge another.) The line builds fast, so even 5-10 minutes makes a huge difference! It starts running around 7, and our last day they started a little earlier. Yes, it's early! But it did put us at the front of the pack at Epcot and HS. On our Epcot day, we were 2nd back from the turnstiles and walked directly on Remy and then walked on Frozen as well. At HS, we were probably 3-4 back from turnstiles and walked directly on Rise and then walked on TSM.
