This was our second DCL cruise and we traveled with another couple - all without children. From an adult perspective, this cruise has a lot to offer even if it seems to be very much pointed towards families with kids. We found the small number of children on this cruise to actually be kind of sad - since we love watching them get so excited about Mickey and all the activities to do onboard.
Embarkation was fast and efficient. I can't say enough about the superlative customer service experience on this ship from start to finish. Our friends noted that this is the first cruise they have taken, where on disembarkation, they felt just as loved as the first day. Usually, there's a rush to just get you off the ship. They also enjoyed the less 'nickel and dime' feel you end up paying for on other cruise lines.
Entertainment was top notch - can't say enough about it. Yes, it was mostly PG, but we come to appreciate that more in this current world. We even laughed when we were watching one of the adult movies one night, and someone actually cursed - it was jarring to hear that again.
