They are staggering park opening times, so I'm guessing more buses will be able to service each park, allowing fewer passengers per bus without increasing wait times extraordinarily. We'll be driving our rental car as much as possible, but I'm guessing we'll take our chances on a bus to MK.
Why not worry about your own safety. If riding the skyliner, keep your mask on and sanitize your hands when you get off. Simple solution.
We were at Universal last week and when riding Hogwart's Express, you were given your own car, and you had to keep your mask on. Hand sanitizer was given to you before boarding. They were not cleaning each car between rides. When we got off we used hand sanitizer.
