We booked the Anthem because we were excited about the food, the ports of call, the ability to roller skate at sea (we do a lot of it at home), the kids club and babies nursery, and so on.
The good:
1. Though we don't care much about entertainment, the portion we saw was really top notch, and largely original. Spectra's Cabaret, in particular, was spectacular.
Very pleasant setup, with a genuinely huge balcony. We were originally traveling with my parents and they would have had the adjacent stateroom, with the ability to open the divider between the two.
Convenient and porters were on it, but check-in was too slow.
