The Princess mini-suite is larger than our Cat 11 ocean suite on Fantasy = 220 sq ft. cabin and 30 sq. ft. balcony. But I have to say, that cabin felt HUGE!!! (Especially compared to my first cabin = oceanview).
We have booked a Cat 11 suite on Triumph = 275 sq. ft with a 65 sq ft balcony which will seem huger still. Comparable in size to a Princess mini.
Thanks for the info - I'll have to remember to book a Princess mini-suite some day.
