Just take the stroller up the elevator as strollers are not allowed on the escalator. You do not have to fold them to ride. My DS uses a stroller as a wheelchair. They have taken the middle section out of the monorail cars so there is more space now. The only time you would need to fold it is if the monorail cars are packed. As far as AK goes, we had good luck with the bus last time. If you have an early ADR before park opening or close to it, you are better off taking the bus. For DTD, I would go to the TTC to get a bus there or spend a few dollars on a taxi if you don't have your car.
