The Disney Skyliner policy for strollers is one of the most parent-friendly in the parks. You do not have to fold a single stroller (or a tandem "long" stroller) as long as it fits within the cabin's floor space, which is roughly 30" x 48". You can simply wheel the stroller directly into the gondola, and if your child is sleeping, they can remain in the seat. This is a significant advantage over Disney buses, where all strollers must be folded before boarding. However, there is an exception for side-by-side double strollers; because of their width, these almost always must be folded before you enter the cabin to ensure they fit through the door and leave room for other passengers. Additionally, if you are using a wheelchair-accessible cabin with an unfolded ECV or wheelchair, you may be asked to fold your stroller to ensure there is enough clearance and that the weight limit (about 10 passengers) is not exceeded.
