If Jim Hill's constant 'leak' of a Monsters Inc. door coaster is correct for the past 17 years. Then once it is finally built and open, we can claim it took over 20 years to construct it!!Biggest example is Frozen at DLP. Announced in 2018, construction began in 2022 and opening in 2026. 4 years of actual construction and 8 years of development. At least with Cars, we know construction is beginning next year, so it'll be interesting to see how long until it opens. Will it be 2026, or 2028 (2027 is being reserved for Tropical Americas)?
