We got to the Skyliner about 7:40 and was able to walk right on both at the Pop station and then the Caribbean Beach station. I wanted to make sure we didn’t have to rush to get there. We used the Skyliner quite a bit on our trip. The day before our first reservation, I talked to a cast member at the Skyliner about our early dining reservations at both resorts to see if riding the Skyliner would be an option (if not, I was just going to get a cab) and he confirmed that they try to have it running so people can use it for those very early dining reservations. I just had to show them my dining reservations information. Obviously, things could change at any time, but we were able to use it for both of our reservations without issue. Maybe if you are using the Skyliner beforehand, you could ask as well. That way, if they have changed the operation, it gives you heads up to use a backup plan to get there.
