Disney’s newest digital service, Disney Genie, is launching on October 19 at Walt Disney World Resort. The service, first unveiled in August, is an update to the company’s earlier line-reservation tools for Disney’s parks, allowing guests to plan and update their itineraries, book time slots for the most popular attractions, and optionally purchase paid access to the fast lanes’ “Lightning Lane” entrances, either à la carte on top attractions or through the “Genie+” add-on.

The service will replace Disney’s older FASTPASS, FastPass+ and Disney MaxPass services, as Disney Genie will roll out across Walt Disney World Resort and Disneyland Resort, the company said.

At the core of the Disney Genie experience is a smart trip-planning capability that maps out a personalized itinerary based on which rides, attractions or food and entertainment experiences guests want to make sure to do while at the parks. That means Genie users can customize their day based on not only the top attractions, but also their general interests — like whether they need to incorporate Princess meet-and-greets into their day, or if they’d rather seek out the best cocktails at the park’s bars, for instance.

Before Genie, guests could make up to three reservations in advance of a park visit through the FastPass+ scheduling system, and could then continue to make reservations through the My Disney Experience app after those first three reservations had been used. But this free system made it difficult to get reservations on top rides, as it favored Disney resort-goers who could book 60 days in advance, while others got a 30-day window. It also didn’t make all top rides (aka Tier 1 attractions) available for the initial booking.

With Genie’s WDW launch on October 19, guests will be able to choose from the two paid options — either individual access to up to two Lightning Lanes or Genie+’s broader selection.

Disney says the following rides are available for the à la carte option: Seven Dwarfs Mine Train and Space Mountain at Magic Kingdom, Remy’s Ratatouille Adventure and Frozen Ever After at Epcot, Star Wars: Rise of the Resistance and Mickey & Minnie’s Runaway Railway at Disney Hollywood Studios, and Avatar Flight of Passage and Expedition Everest at Disney’s Animal Kingdom.

While picking two options could help speed up your wait times, it may not include your must-have ride selections.

Disney Genie+, meanwhile, opens up Lightning Lanes at a total of 40+ attractions across the four parks instead, including many more of the Tier 1 rides. It will be priced at $15 per ticket per day at Walt Disney World Resort and $20 per ticket per day at Disneyland Resort, when available.
