Greetings, Yolanda!
Thanks for bringing your question to the Disney Parks Moms Panel. I'm so excited you are planning a trip to visit the Disneyland Resort. Like you mentioned,
Pixar Fest will soon be coming to a close at the Disneyland Resort on September 3, 2018. While favorites like the Pixar Play Parade and Paint the Night Parade are sticking around after the festivities conclude, other experiences will be finishing on the final day. Many of the my favorite parts of Pixar Fest were actually the amazing food items themed to Pixar films and Characters. For example, the adorable little green men macarons from Alien Pizza Planet and specialty Churros like the Coco-inspired churro were part of these exclusive festival foods ending on September 3rd. It also appears that the amazing fireworks show
Together Forever - A Pixar Nighttime Spectacular will not be continuing past the final day of Pixar Fest.
Starting September 7, 2018 all-new exciting experiences will be making their way to the Disneyland Resort.
Halloween Time will be kicking off in both parks with an array of spooktacular entertainment, themed attractions and decor, as well as new autumn-inspired foods. Also, the return of the dazzling show "Remember...Dreams Come True" Fireworks Spectacular will be heading to Disneyland Park at this time. This is one of my all-time favorite fireworks shows, because it celebrates the history of Disneyland.
No matter when you come, there will be plenty of magical experiences to be had. I hope this helps, and have a magical day!
