Hello! Trying to prepare for our May 2022 trip (YAY!) and this is the first of many questions, I'm sure. For experts - can you take a stroller on the water taxis? Do you have to fold the stroller up to take it on? Can you take an unfolded stroller on the Hogwarts Express? Only asking as I'm sure we're going to load our stroller up with stuff, and I can plan better if I know I'll have to remove everything before boarding. Thank you!!
