Yes, Disney Genie+ (which was rebranded in mid-2024 to Lightning Lane Multi Pass) can and does sell out in 2026. While the "base" Genie service is a free planning tool, the "Multi Pass" which allows you to bypass the standby lines has a limited daily capacity. On peak travel days—such as Spring Break (like today, March 1), Christmas week, or major holiday weekends—the service can sell out as early as 10:00 AM. In 2026, Disney uses dynamic pricing, where the cost can range from $15 to over $35 per person depending on the date. To ensure you get it, you should purchase it as soon as the "window" opens (usually at midnight on the day of your visit for single-day guests, or further in advance for resort guests). If it sells out, you are stuck with standard standby lines for the rest of the day. Additionally, the "Individual Lightning Lane" (Single Pass) for the most popular rides like TRON Lightcycle / Run or Rise of the Resistance often sells out even faster than the general Multi Pass.
