Two things may be making the CLS the same as a GS.
1. The aft facing cabins you listed are noisier on the balcony with no privacy, since it faces the sports area with the "boom...boom...boom" loud music and sports activities.
2. Some don't like the interior stairs to get to the bedroom with CLS cabins.
IMHO...I love the location of the CLS cabins, and enjoyed ours...but still would prefer the layout of the GS instead, which is our go to cabin on Oasis class. Problem solved with Wonder though, best of both worlds. 🙂
