A few years back we did Miami to San Diego through the Panama Canal on Infinity and stayed in CS 8106. We thought it was awesome for our needs. It has not been updated yet as far as I am aware. Positives: The M-Class CS is quite spacious and is blessed with a great view. Great being able to cruise in hot or cold climates and stay indoors with that view. We enjoyed the separate bedroom, the wall of windows, the great storage space, and the indoor dining table. Some negatives that some people mention: one bathroom which requires a walk through the bedroom, the aforementioned high tub (mobility restricted), the narrow (but adequate) balcony. The CS is not a "premium" suite and gets the same Retreat benefits as a Sky Suite.
