Hiya, Christina, and Welcome to planDisney! Thanks so much for stopping by and asking this question.
Making a schedule with superheroes when they're always busy saving the day or even the whole galaxy can be a bit challenging! Sometimes schedules aren't released very far out, but it would be extremely unusual for
Avengers Campus to be deserted. I checked the
schedule for Wednesday, April 27th which is one week before your arrival date. Based on that schedule, I think it's safe to assume all of the Avengers will be in action on campus for your visit on May 4th. While the schedule and appearances could vary slightly, I think you could use it as a guide as you are planning. As your arrival date nears, there should be a schedule listed for Avengers Campus at
Disney California Adventure Park.
Guardians of the Galaxy - Mission: BREAKOUT! is my favorite attraction at Disney California Adventure and is not-to-be-missed! I could ride this over and over again! I also highly recommend experiencing
WEB SLINGERS: A Spider-Man Adventure! For this attraction, you can either wait in the standby queue or purchase an individual
Lightning Lane entry to have a shorter wait time. Once you have entered Disney California Adventure, you can purchase Lightning Lane access through the
Disneyland app. One tip I have for you is to place a
Mobile Food & Beverage Order just before you enter this attraction and choose an arrival window for the time frame that you anticipate exiting. Trust me when I say that you're going to work up an appetite and
Pym Test Kitchen, conveniently located next to WEB SLINGERS, has some of the best snacks! Our family loves the Quantum Pretzel and the Celestial-sized Choco-Smash CANDY Bar!
I hope this information helps ease your mind about catching your favorite superheroes in action at Avengers Campus! Whether it's Spider-Man swinging through the air, the Guardians of the Galaxy dancing around, or the Warriors of Wakanda marching in, I have no doubt you will see the Avengers assemble!
Wishing you a fun-filled visit at Disney California Adventure!
Smiles,
Lisa
