We went the first week of May in 2018. During Starwars May the Forth. It was a lot of fun. Space Mtn gets the Starwars overlay to Hyper Space Mtn. Lots of Starwars things going on starting May 3.
Unfortunately there was a grad nite during our trip, and before DCA opens for grad night a bazillion gr 12’s are in DL that night. We had a 5 day ticket so it didn’t affect us much but if you’re only there 2-3 days I’d find out when the grad nite is and avoid it.
