Summary (TL;DR)

• Disney Premier Access is the paid “fast track” service at Disneyland Paris, replacing the old free FastPass. It comes in two types: One (per ride, per person) and Ultimate (once per included ride, per person). Official
• Prices are dynamic. Premier Access One starts “from €5 per person per ride”; Ultimate starts “from €90 per person per day,” varying by date and demand. Official
• It saves substantial time on the busiest days and for high-demand rides, but often isn’t necessary on low-crowd days if you rope drop, use Single Rider, or Extra Magic Time.
• Best value: one-day trips, school holidays/weekends, late arrivals, or families aiming for multiple headliners. Worst value: midweek off-season visits with early starts and flexible plans.
• You buy and manage it in the Disneyland Paris app (Ultimate can be purchased in advance; One is typically day-of after park entry). Official app

What Is Disney Premier Access? Disney Premier Access is Disneyland Paris’s paid service that lets you enter a dedicated, faster queue at select attractions—replacing the former free FastPass program. It doesn’t “skip the line” entirely but typically reduces wait times versus the regular queue. Availability is limited, and access times can sell out on busy days. Official

The short answer

• You don’t need to reserve most rides at Tokyo Disneyland—standby is the default.
• The only ride/show “reservations” are:
  • Disney Premier Access (paid, timed access) for select rides and parade/spectacle viewing.
  • Entry Request (free in-app lottery) for select stage shows and some character greetings.
• Table-service restaurants use Priority Seating (advance dining reservations).
• Almost everything is managed in the Tokyo Disney Resort App after you enter the park; dining can be booked before your visit.
