The Skyliner will run in rain, just not high winds and lightning. We were at the CBR hub one time and Skyliner shut down because of lightning. It was sunny all around, but if there is a lightning strike within 10 miles (I think that was the distance the CM told us), they have to shut down. They brought buses and took us to where we were going. And if you're staying at a Skyliner resort you can check the transportation tab on your
MDE app to see if it's running. If it's not running, it will say "Skyliner not available use bus transportation" or something like that right next to . Unfortunately, that's not well advertised, so most people don't know they can check there. I only used that feature when we were actually at the resort and getting ready to head to DHS or EP and couldn't see the Skyliner from our room. I'm assuming it works even when you're at the park, but never tried it.
