EMH for onsite hotel guests is always in the main park only, except on well-advertised-in-advance dates where its the Studios instead.
During EMH in the main park, in Fantasyland the Carousel, Dumbo, Teacups, Peter Pans Flight, and usually either Pinocchio or Snow White ride. In Discoveryland its Buzz Lightyear ride, Space Mountain 2, and Orbitron. If any of these rides are on the published refurb/closure schedule for your dates, obviously they won't be open for EMH either.
