Tickets are available with no wait on the Disneyland app... go to Tickets and Passes > Buy Tickets > Special Event Tickets and both Throwback Nite and Star Wars Nite tix are there for purchase! So far they aren't sold out on any night as of 1:58 pm. EST. Stay in the queue if you are waiting, but check the app (have your account signed in, or create one if you don't have one yet) and it may work for you! I got two tickets to May 4th's Star Wars nite event! First time getting to be with other Star Wars fans in the park on that special day!
