At least for now, Typhoon Lagoon is scheduled to be the evening EMH park on that day. July 1st is a Saturday, and that is not a night where Disney seems to be scheduling many EMH evenings. There are literally no evening EMH parks on any Saturday night, even during the busiest of times, except for Typhoon Lagoon. This could, of course, change between now and July, but since it isn't just a phenomenon of that particular week, I wouldn't count on it.
P.S. I have the EMH hours done in a calendar format (a Word document) if you'd like to see the pattern, or if that would just be easier to read (I think it is). PM me your e-mail if you'd like a copy.
