Not always, it is Florida and weather changes quite quickly, and weather 10 miles away we can't even see does impact SkyLiner.
I am only advising from experience. Last month we were in EPCOT heading to the SkyLiner to get to our reservation at CBR. We were then going to return to EPCOT for the rest of the night.
Far off lightening popped up and within view of SkyLiner it was shut down. It is just like any of the outdoor rides, if lightening comes within so many miles (I believe it is 10), it gets shut down even if we are not experiencing bad weather.
We had our car so we had to hustle to get ourselves out to the parking lot then drive to our ADR. Had we had to get out front to the bus depot and then wait for a bus to be dispatched to CBR (normally not) then we might have missed our ADR.
