Many years ago I went to Euro-disney in Paris. It was great fun and not that crowded, I don't think the Frenchies really liked the Americanisation of it all. I had a two day pass and one day must have been a weekend as there were many more people than the first day. The interesting thing to me was the way they had different setups to arrange the entry queing based on how long the que was and also they ran the rides that you travelled on conveyor style things at different speeds to suit numbers. It was also pretty funny to see Smith Family Robinson tropical island with snow on it.
