I am planing a June 2020 trip, trying to figure out how much of an impact the Magic Kingdom early morning event has on rope drop. It seems like the time frame we are going Magic Kingdom has an early or late event happening.
Overall it should not be a tremendous impact. However, if you’re going to FL you’ll notice that impact more than anywhere else since that is where the event occurs. If you can make another land your focus for RD that day, you won’t probably even notice.
