We are taking our 1 1/2 year old and 4 and six year olds to Disney. We will be using the monorail for our main transportation. I'd like to bring the little one's regular stroller instead of an umbrella (b/c it's so much easier to push and manuever). Is it a problem getting on the monorail with these? My other option is to bring the umbrella and leave it somewhere inside the Magic Kingdom and rent a stroller there for the day to use in the park. Is there a place I can leave it? Thanks! I am learning so much from all of you!
