OP was asking about DHS - but, yeah, DLR is doing way more Star Wars in May, including Hyperspace Mountain and
Star Wars Nite on the 3rd and 4th (and the 27th to coincide with Celebration). Honestly, Star Wars Nite is something I could kinda get behind DHS doing if WDW starts doing After Hours stuff more frequently.
(I'm kinda curious to see how late DLR keeps ROTR open during that event, since ROTR normally closes at 9pm, even when the park is open until midnight. Makes me wonder if they'll open it late the next day, since it seemingly still has a long maintenance schedule.)
