Discoveryland is Disneyland Resort Paris’ unique version of Tomorrowland in a steampunk meets classic technology concept. It is very similar to the Tomorrowland with a version of Space Mountain and Star Tours (closed for refurbishment) and Autopia. The tour of Jules Verne’s Les Mystères du Nautilus is a great addition and really nice if you have memories of the 20,000 Leagues Under the Sea: Submarine Voyage ride from the Magic Kingdom (1971-1994).
This may explain why the mantra/motto “Here you leave today and enter the world of yesterday, tomorrow and fantasy” was changed to “Here you leave today and ether worlds of history, discovery and ageless fantasy” for this park.
