I was in the tower and the corner rooms are the larger rooms. It was large enough for four (two were kids) and they provided a cot for free; I was there at a peak time as well
the view was fantastic on the higher floors (can't recall what floor I was on)
I was curious about the cabanas and from what I saw they were regular rooms and if you liked being right on the pool that was a good location if you could get a lower floor room with a deck to the pool.
I don't know if the corner rooms were better there or not though
