TL:DR: If you are reading these reviews purely as a first timer: Do it! It is a fantastic experience that is worth trying once. We will be doing this again.
We just alighted from our first cruise, and I wanted to tell you all that are curious about it, that it is fantastic. It's not perfect, but nothing in this world is. Take it for what it is, and embrace the situation.
Avoid the whining reviews from the entitled parents, self righteous regulars and cranky old people. Most of them in these reviews that are negative basically seem to be demanding or wanting more than they are willing to pay for. (ie:If you want a rolls royce service, buy the most expensive cabin and spend lots of money)
Cabin was Large and spacious. Balcony was fantastic and had great views. Lounge area was comfortable.
Ensuite was great. Walk in Closet was fantastic
