This is my biggest complaint with the bungalows, I think the roof should have been the same red roofing used on the rest of the resort. I also think it odd they are painted a slightly different color than the longhouses. I like how the bungalows look, I just wish they blended better with the main resort. They remind me of an addition to a historic house, they look similar to the original design style but there are enough subtle differences you can tell they are an addition, they don't look bad, they just don't look quite right.
For a company like Disney that is famous for being so detail oriented it's a bit disappointing.
