With an estimated 1 million passholders, there would have been an impossibly long virtual queue of die-hard fans waiting anxiously to snag an online advance reservation for Disneyland's reopening day. Annual passholders comprise an estimated 50% of Disneyland resort attendance, according to UBS financial analysts.

Disney does not publicly release exact percentages, but industry estimates for 2026 suggest that Annual Passholders (now called "Magic Key" holders) make up roughly 30% to 50% of the daily attendance at Disneyland Resort. This is significantly higher than at Walt Disney World in Florida, which relies more heavily on one-time international and domestic tourists. Because Disneyland is a "locals' park" in a densely populated region, the Magic Key program is a critical revenue driver. However, since the introduction of the park reservation system, Disney has capped the number of passholders allowed in each day to ensure there is enough room for "high-yield" guests who purchase single-day tickets and spend more on hotels and merchandise. This balancing act ensures the park remains profitable while satisfying its most loyal fan base, many of whom visit dozens of times a year for just a few hours at a time.
