We had a catagory C suite on Rhapsody and there really aren't any amenities, just a nice good sized cabin, nice balcony and we actually had a bath tub :-)
You will love the cabin and this new ship looks absolutely beautiful, enjoy!
Same here...we had a cat.B on the Enchantment and there aren't any extra amenities except an incredible cabin. No priority boarding or disembarkation. Must wait in the same line. Though, I believe on the Explorer there are a few extra such as an honor bar but I'm not sure. Have fun
When we were on Vision of the Seas, in a CatC, they had a seperate embarkation desk for suites. We just happened to stumble across it. Didn't know about it in advance.
Other than that no extra onboard amenities.
