Here's a good HS Guide:
Micky & Minnie's Runaway Railway - Ride is practically identical to DL version, but the queue is way less themed.
Frozen Sing-Along Celebration - This is a fun show unique to HS.
Indiana Jones Stunt Spectacular - Old show but it is unique to HS and worth a watch if you are a fan.
Star Tours: The Adventures Continue - Identical to DL Tomorrowland version, but the outside is more heavily themed.
Muppet Vision 3-D - This used to be at CA but was replaced with Mickey's Philharmagic - it is the same though.
Rise of the Resistance - Identical to DL version.
Milennium Falcon: Smugglers Run - Identical to DL version.
Alien Swirling Saucers - This is the same ride system as Mater's Junkyar dJamboree at CA, but it is covered.
Slinky Dog Dash - Totally unique roller-coaster and worth riding, It will have long watis so plan accordingly.
Toy Story Midway Mania - This is identical to the CA version except it has a second full track for more bandwidth.
Walt Disney Presents: One Man's Dream - cool little museum with a short film - it may show a movie preview though.
Beauty and the Beast - Live production in an outdoor amphitheater - there is cover over the front section.
Rock'n Rollder Coaster - Indoor cosater with lots of corkscrews - it is unique to HS (compared to DL anyway).
Lightning McQueen's Racing Academy - Just a little show with an animatronic Lightning on a lift and screens.
Twilight Zone: Tower of Terror - The original and worth checking out because it was always the better version.
Fantasmic! - The same but different, there is seating in a HUGE amphitheater. The set is more epic. With changes over the years, it is somewhat different from the DL version. It's worth a watch if you are a fan or miss it at DL right now.
That about covers it I think. HS has always been a show-heavy park, though many shows are still dark since COVID.There was the Disney Jr. Dance Party that was similar to what is at CA, and a live Little Mermaid which was one of my favorites, but sadly seems to bever be coming back. I think there is enough unique stuff to enjoy though - have fun!
