Another question - how does a suite compare to a balcony? How much bigger etc?
It depends on the ship and the category of suite. On the Fantasy class the "grand suites" (formerly cat. 12) are 330 square feet with a 70 sq. ft. balcony. The regular suites (formerly cat. 11) are 220 sq ft with a 30 sq ft balcony (plus they are not at all private).
On the Freedom the suites range from 245 to 300 sq ft.
