For no particular reason: here are the average maximum-queue times for the three biggest theme parks in Europe (10 busiest rides only), in 2023.
Some interesting insights about capacity planning to be gleaned from this; visitor numbers from 2019 are 9.8 million for Disneyland Paris, 5.8 million for Europa Park, and 5.4 million for the Efteling, so not *that* far removed.
(Of note: of these parks, Disneyland Paris is the only park with a paid fastpass system)
These statistics all come from https://queue-times.com/, which aggregrates queue statistics from many parks; I'd recommend looking there if you want the full data.
