The entertainment was very lame and few passengers even bothered going to the shows. The casino hours were restricted and had a surprise closing as we did not get into international waters as planned. In the casino even when playing $5 a hand blackjack or roulette you have to pay for drinks. Amazingly the entertainment, bars, restaurants, and other services start closing at 8:30 and everything is shut down by midnight which feels like 6:00pm or earlier for those of us coming to Europe from the US. In the ships defense, the crowd was so old that by 8:30 there were not many people in the jazz club so I understand why they shut it down. The comedian joked that the HAL crowd was so old they held the midnight buffet at 2 in the afternoon and unfortunately he was not far off.
The ship has odd rules about bringing bottles on: only two bottles per passenger and then they can only be wine or champagne. So you can't bring beer or spirits on the ship but you can bring on wine to avoid the $50 or so per bottle at dinner.
We only visited one Norwegian Fjord and couldn't get to Eidfjord so we made a surprise (to the town) stop at Haugesund arriving in the afternoon when almost everything closes about 4:00.
Awesome wrap-around deck and plenty of room. Note that this cabin has a connecting door to 6173.
