The Celebrity Edge class ships have an amazing suite option. We have sailed in a Sky Suite (twice) and the cost to benefit ratio is super. You pay more than a regular cabin but not nearly as much as with some other lines. The ship-within-a-ship concept is real on these ships. As part of your fare, you get extra amenities and well-equipped cabins. The exclusive Luminae restaurant is fine, but the food is a bit Frency (heavy). But we also had access to Blu (Aqua Class) and the food is lighter and superb. We also ate at the main restaurant a couple of nights when the choice met out liking.
The standouts were our butler and housekeeper. I had a bad cough and had to visit the ship's doctor (You cannot self-medicate unless you bring your own stuff -nothing is sold on-board). That required a covid test (fortunately negative). I got antibiotics and OTC medicines and had to isolate in my cabin for 24 hours. I still have not seen a charge for this. The housekeeper managed to clean the cabin while I was on the balcony, and the butler brought me all my regular meals (no "leave it at the door") as long as I stayed outside when he was there. When I was released the next day (after another negative test), many of the staff specifically asked how I was. They all took an interest.
Another benefit from the butler was disembarkation. We had to leave the ship very early to get to the airport. He personally gave us a wakeup call. Carried our bags from our cabin, saw us through the disembarkation process, and dropped us right at the taxi. He was more like a son than a butler.
The bath was spacious and well equipped although, like most ships, the shampoo, etc., were in large and similar bottles and a bit awkward to handle. We liked the separate enclosed toilet room. The room lights and curtains could be operated from your phone or a wall mount. Lots of room, and quiet. A big plus is that the bed faces the balcony, so you can lay in bed and see the sea.
