Sky suite is definitely the way to go!
Make use of your butler. They are there to please you!
We had Ben back the beginning of March. We had him bring us coffee and danish with juice and a fruit plate. Switched it up one day with just a phone call-Frosted Flakes with a banana! LOL.
I love the extras- Retreat Deck; Retreat Lounge.
We did not go to Luminae, because the MDR's are all aft. It was just easier to just drop down to 3 and go to Normandie. Of course, then it's right up to 4 for the casino.
Have the best time.
