I dont have a current list of which ships are selling the FTTF (faster to the fun) for $50 per cabin, but they are selling VIP, with earlier cabin access and some other perks included. Maybe Miracle will have it by this summer? Then you can keep you balcony and still get boarded early.
That way you dont have to wait until 1:30 to get into your cabin either. They limit how many cabins can buy it so you might want to keep a eye out for it.
