Mansion rooms are more "formal" in appearance. More along the line of POFQ in decoration. Bayou is "down home" cabin type. Homey comforters, log beds, very cute. Otherwise, they have ALL the same amnenities, except the trundle bed in the bayou's. Exactly the same bathroom, sinks, closet area, safe, tv, fridge, armorie, table type, bed size, light avaiblity, window's, etc... . Everything.
Both are nice, I like the inside of the bayou and the outside of the mansions. I like to rotate between the two, feels like staying at 2 different resorts.
Hi. I just wanted to add that the Alligator Bayou section has the trundle beds. If you need a room that sleeps five this is the section you will be in.
