The mini suite is about 100 square feet bigger or so, with full bath (no shower), and a larger sitting area and closet area. Also, the way the decks are built is "wedding cake" fashion. This means that the mini suites, which are at the lower end of the "cake" have balconies that are exposed from above. People can look down on you. I've had balconies a few different trimes, and min-suites twice. I would opt for the mini suite since it is bigger and my experience has been that the people on the balconies above don't spend time looking down at you, so I wouldn't worry about that personally.
