Welcome to cruise-chat.
Do you mean a category 12 suite? We've stayed in a cat. 12 on the Holiday 3 times...soon to be 4 times. They really aren't suites in the classical sense since they are just one big room. But we like them because they have lots of floor space, huge sofas, large balcony, walk-in closets, and good sized bathrooms with tub. We think they are worth it, but then again we could probably take two cruises in standard cabins for the price on one cruise in a cat. 12. It really depends on how much value you place on space. Most people don't spend much time in the cabin so size isn't important to them. We spend time in the suite and find them very relaxing.
