Well, it's all personal taste, but HS has some great stuff in it and the impact of the construction is somewhat overblown. It is show heavy, so if you aren't to into that, then it could be an issue. A lot of us here have seen these shows over and over so are sometimes dismissive of them as a real draw, but if you've never seen them then they are brand new to you. If you have Star Wars lovers, then the Galactic Spectacular is a must do. Fantasmic! is also a great show, though it is hard to have time for both in one night. For the young one, the there is the Disney Junior show. So, writing off RnRC you still have at HS:
Rides:
Tower of Terror
Toy Story Mania
Star Tours
Shows:
Voyage of the Little Mermaid
Beauty and the Beast
Frozen Sing Along
Indiana Jones Stunt Spectacular
Muppet-Vision 3-D (edited to add this)
Fantasmic!
Star Wars: A Galactic Spectacular (plus the March of the First Order and other Star Wars show they do on center stage throughout the day)
Jedi Training Academy (and kids can participate!)
Miscellaneous:
Star Wars Launch Bay - exhibits from the movie
Walt Disney Presents - exhibits from Disney history and a short film about Walt or a movie preview for an upcoming film - film is optional either way
Yeah, it's only three rides, but it's three of the best rides. Ideally, if you had Park Hoppers, then HS makes for a good half day even if just to see one of the nighttime shows. The decision is yours and it's certainly reasonable to call a skip after considering all the facts. You'll have fun either way. Enjoy your trip and welcome to the Dis (love your avatar too)!
