As mentioned, strollers have to be folded up to ride in the tram. The same goes from the train (when it's running); strollers can be brought aboard, but the child has to be out of it and the stroller has to be folded up. Early in the day, it wasn't too bad, but by evening, when the stroller was filled with stuff...sigh...that was a lot work to unload everything for the tram ride back to the parking structure...
