It's not hard. It ebbs and flows. Sometimes it's busy, sometimes it's not. In all the years since the resort has been open, we have never not been able to board a monorail (and we stay there every year). Might be a challenge during super busy weeks like Christmas, but with the walkway now open, there are more options for people. Obviously, peak periods of day (like in the morning just before park opening) can be the most crowded.
