We usually roll the stroller right onto the monorail - it's so much easier than having to fold it up (esp. if you have alot stashed in the stroller basket like we usually do). Our stroller is decent sized though, doesn't take up too terribly much room. It's also nice because if it is crowded,ds sits right in the stroller instead of taking up a seat an adult can be sitting in. (He's 2 1/2)
