The mini-suite staterooms are without a doubt nicer, and bigger (for example they have a sofa in a separate sitting area) so are the balconies, except that the balconies are not as private as some of the non-mini-suite ones. look at the deck plans to see the differences in size and layout, and decide what you want, take into account the price difference and go for what you decide on. You can read my review on this thread of a balcony room on the Crown to get an idea of that.
Landlocked in Denver, but cruisin every chance we get.
