The simple maths
- List the visits you’d realistically make in 12 months, and on which dates.
- For each visit, add up the online day-ticket price for everyone who’d go.
- Add parking if a pass includes it (some premium passes do).
- Compare with the total cost of passes for the same people.
If the passes cost less, and the dates you’d go aren’t excluded, the pass pays off. Anything extra is a bonus.
Things that catch families out
- Exclusion dates: cheaper passes often exclude school holidays and weekends in peak season.
- Pre-booking: many passes still need you to reserve each visit, with limits on bookings at once.
- Changes: attractions can be added or removed. For example, Blackpool left the Merlin pass.
- Monthly plans: may include a joining fee and a minimum term.
Passes worth comparing
- The Merlin Annual Pass for LEGOLAND, Alton Towers, Thorpe Park, Chessington and more.
- National Trust or English Heritage memberships.
- Local zoo memberships, which often pay off in two or three visits.
- US: the America the Beautiful pass for national parks.
