@ejgonz2 Strollers are expected to be allowed on the Skyliner without folding. Whether 2 will fit might be a question - though if your party is a total of 6 with 3 in strollers, that probably will fit; the bench on 1 side folds up making more space for the strollers or
ECVs/wheelchairs, and the 3 guests not in strollers can use the other bench.
One thing I have not heard is whether there will be a size limit for strollers or ECVs/wheelchairs on the Skyliner. Presumably some limit, but the 30" x 48" mentioned by DanBoris is specifically for buses and due to ADA rules about tie-downs. I don't know if the monorails or boats on WDW property have the same size limits for mobility devices as the buses. Width may be the most limiting factor, and I'm not sure if there has been an official measurement posted for the width of the opening into the gondola cars.
But IF they do limit to the 30" x 48" box, that is smaller than the size limit allowed into the parks -- which for strollers is 31" x 52" for strollers and 36" x 52" for mobility devices. So some strollers may still need to be folded if they stick with the box size.
