They are bit quieter if you compare to the Nemo suites with a view on the pool. Everything else is the same, including the time it takes from the Lobby/Landscape of flavours to the door of the buildings.
Lion king is usually less expensive than Nemo when you’re choosing upfront . i personally found the lion king rooms to be dingy/ dull/dark compared to the fresh blue of the Nemo rooms .
i would pick Nemo because I like the brightness of the blue theme
