Hello Murphy123. I just responded on your other thread, but to repeat, I did the same 15 day Hawaii cruise this last April, but on Island Princess, and absolutely loved the cruise and the ship.
I have also had midship mini-suites on Diamond Princess and Sapphire Princes and loved them, and the ships as well. Papa Bear hit it right on the head when he said big ship comfort and amenities with a smaller ship feel--never cramped or crowded.
We find the mini-suites ideal; large bathroom with tub and shower; lots of closet and drawer space, which comes in handy on a 15 day cruise; large sitting area with sofa, table and chair; and a very large balcony with two chairs, two recliners and two tables. We didn't do any entertaining, but as Papa Bear said, you will have the room if you wish to.
So you're in for a great cruise in a great cabin on a great ship. Keep in touch.
