I have only cruised Carnival and in a balcony cabin. In the six solo cruises I have done five have been at 200% of the fare and one was at 160%.
Solo cruisers have to pay the full 200% for certain category cabins and up, but you can get 1A's and some inside for less than the 200%.
Good luck in selecting your cruise, you'll love cruising solo!
