Frequently asked methodological queries
Why do Legoland Billund, Puy du Fou, Tivoli Gardens and Ocean Park rank below their reputation?
Because this index ranks all-round parks and weights rides heavily — thrill alone carries 33% of the total. Four kinds of park are affected. Purpose-built young-family parks: Legoland Billund Resort, whose thrill score of 6.4 is accurate rather than an error, since its four coasters are all family-scale with no launch, hyper or inverting ride. Show-driven parks: Puy du Fou, which runs almost no rides by design and is judged worldwide on its live productions. Heritage and garden parks: Tivoli Gardens, a 19th-century pleasure garden whose appeal is setting, gardens and music rather than ride count. Marine-life and animal parks: Ocean Park Hong Kong, and to a lesser degree Chimelong Ocean Kingdom and Disney's Animal Kingdom, where much of the day is spent on animal exhibits this index does not count as attractions. The specialisation allowance raises the lower of a park's thrill and family standings when the two differ substantially, which helps but cannot fully offset a third of the weighting. A second factor compounds it for some of them: Tivoli Gardens, Puy du Fou and Ocean Park Hong Kong have no public wait-time tracker coverage, so they receive the neutral crowd score — it neither helps nor hurts, but it leaves 15% of their total inert while other parks are genuinely scored on it. Finally, thrill ratings are assessed holistically rather than derived from a purely spec-based formula, so they cluster in a narrow band and differentiate less between mid-tier parks than the other factors do. All of these parks are excellent at what they set out to do; this is a stated limitation of the model rather than a judgement on them. If you are travelling with young children, or for shows, gardens or animals rather than coasters, read the family and value columns instead of the overall rank.
How is the overall score calculated?
Each park's overall score is the weighted average of four criteria — thrill factor (33%), family friendliness (33%), value for money (19%) and crowd & wait management (15%) — rounded to one decimal. Before weighting, each factor is standardised so all four have the same spread across the 50 parks. A specialisation allowance then applies: not every park is attempting the same thing, so where a park's thrill and family standings differ substantially, the lower of the two is partially raised. That rule is applied identically in both directions and to all 50 parks. Where a park lacks reliable public data for a criterion, it is scored conservatively rather than excluded.
Why do thrill ratings look compressed compared with the other factors?
Thrill is assessed holistically, not generated from a purely specification-based formula. Height, speed and inversion counts can be measured, but they do not capture pacing, airtime, terrain or overall ride quality. The live ratings are therefore kept in a deliberately narrow band (mostly 6.0–9.0) to avoid publishing a false sense of precision. That compression is an honest reflection of judgement uncertainty, but it also means thrill differentiates less between mid-tier parks than family, value or crowd scores do. The same score is used across the site, so no page shows an inflated or deflated version of it.
Where does the data come from?
Rankings are aggregated from public review platforms — including TripAdvisor, Google Reviews and Theme Park Insider — alongside published attendance figures and operator ride databases. Wait times come from Queue-Times.com, which publishes per-attraction season averages from live queue tracking. Planning details (hours, ticket and pass pricing, transport, dining, accessibility) come from each park's official website. Records come from public record-tracking sources such as Guinness World Records and the Roller Coaster Database (RCDB). Nothing is independently verified by ParkRank, and nothing is pay-to-place.
How is wait time calculated?
One basis is used for every park: the unweighted mean of the 2025 season average posted queue time across every tracked attraction in the park — an all-ride annual mean, not a headline-ride average. Source is Queue-Times.com. Virtual-queue duplicates and retired attractions are excluded, and so is any attraction in its first season, so a new-land opening surge never distorts a park's crowd score. The figure is a planning signal, not a live feed: expect longer queues on peak weekends and school holidays, and shorter ones at opening.
Why do some parks say “Not measured”?
40 of the 50 parks have usable queue-tracker coverage. Nine — Tivoli Gardens, Nagashima Spa Land, Puy du Fou, Dreamworld, Universal Studios Singapore, Ocean Park Hong Kong, Fuji-Q Highland, Chimelong Ocean Kingdom and Warner Bros. Movie World — have no tracker data at all. A tenth, Lotte World, is excluded by our feed-quality screen: its tracker never reports any attraction averaging under 30 minutes, carousels and children's rides included, so it is publishing a nominal minimum rather than a measured queue. Rather than invent or accept a figure, we leave the average wait blank for all ten and give them the neutral crowd score, which neither helps nor hurts their ranking. It is the same treatment applied to parks missing attendance figures. An honest gap is better than a made-up number, and you will never see a value on this site that is not a measurement.
How often is the data updated?
The index is refreshed periodically rather than live. Every page carries a "Data last updated" note in the footer so you can see how current the figures are. Seasonal events list typical months because exact dates shift every year — always confirm dates and prices with the park before booking.
Why isn't my favourite park on the list?
The index is capped at 50 parks worldwide, so plenty of excellent regional parks fall outside it. A park also needs enough reliable public data across all four criteria to be scored fairly — parks with thin review coverage or no published operating information are held back rather than guessed at. The list is reviewed with each refresh, so parks do move in and out.
Are parks ranked against each other fairly if they're different sizes?
Yes — every park is scored on the same four criteria, so a mega-resort and a compact regional favourite can be compared on equal terms. Value for money weighs the effective cost of a day (published gate price plus parking) against the rides a visitor can realistically get through in a typical visit, at roughly three attractions an hour. It uses published figures plus a bounded lineup-quality multiplier (0.75–1.25) built only from externally verifiable counts — coasters by intensity tier, dark rides, marquee manufacturer installations and recorded park records, sourced on one basis for all 50 parks. The multiplier is measured per counted attraction with a minimum denominator of eight, so a very small counted lineup regresses toward the average rather than topping the range. There is no editorial “notable ride” judgement anywhere in the calculation.
Can I submit a correction?
Please do. If a price, opening year, ride count, record or event date looks wrong, email us with the park name and a source and we'll check it against the next refresh.
