Now that this has come up twice, has anyone ever argued that the carpets were anything other than a thematic disaster for very little (if any) benefit? It's also a particularly strange one to bring up, as it's not exactly like Walt decreed an Aladdin Dumbo clone for Adventureland at the MK.
The Tomorrowland Speedway is also an odd one to bring up as I think it's the attraction that people most often mention they'd be happy to see replaced. Yet, that survives while Frontierland becomes, ironically, Carsland.
