Carousell is my hotel of choice.
I've stayed in the 2 room/2 bath suites. It is basically a regular 2 queen bed hotel room, with an additional bed and bath attached. The 2nd room is separated by a regular door and has its own armoire with TV, then through another door is the full bathroom.
I haven't stayed at the Candy Cane so I can't comment on their rooms. But at the Carousel, you are right across the street from the main entrance. With Candy Cane, you've got a farther walk or optional shuttle ride. But in my opinion, by the time you wait for the shuttle and ride it back, you could have already been to your room at the Carousel.
I think the Candy Cane has a better breakfast than Carousel, but you can't beat the view from the breakfast room at Carousel.
