I don’t really care about the resort itself (though I hope you have a good time visiting!
) but I wanted to comment on the design...
The France Pavilion is based on the architecture of Paris, which draws mainly from the Belle Époque and Art Noveau eras general building wise (they run fairly parallel, though Art Noveau was shorter) in terms of general building style. It’s got a hodge podge of Gothic and Renaissance in there cause hey, Paris is olllllllllllddddd.
The Riviera is many hundreds of miles from Paris in Southern France. Southern France has an interesting history in that it has heavy roots dating to the Roman Empire. Therefore, much of its architecture is what is called Romanesque (unlike Paris, which has very little). Along with a smattering of other styles. But Art Nouveau has much less influence in the South than the North.
All that makes me sound like a major nerd (which I am) whose favorite country to visit is France (very true), I know, but the point is that much like in the US, architecture varies from place to place based on history and climate. The architecture of Disney’s Riviera is relatively in keeping with the French southern style. It’s just that less people are familiar with it.
