We sailed on The Spirit. This was a cruise to nowhere. I was told by my agent it was a 24-hour cruise, but it was in fact an 18-hour cruise.
It was very expensive as the cheapest cabin went for 500.00 for two. We got onboard at 1pm, however cabins were not ready till after 2. This meant we had to lug our bags all over the ship as there was no luggage check on an overnight. The food that was included was an Italian cheapo menu consisting of chicken parm, lasagna and eggplant. It was very limited. If you wanted better fare you needed to pay extra in one of the alternative restaurants. We did and had a good meal at the Asian restaurant. I expected to have surf and turf for a cruise of this expense.
Service was slow and poor! There were two shows, both of which were like high school reviews. There was an excellent dance band for the "New Year's Eve party." This was the only upside of the cruise.
We played a bit in the casino, but none of the slots were paying out. The tables were limited and extremely crowded. This was our 15th cruise -- our 4th with Norwegian.
Honestly, this was definitely not worth the money. I would tell anyone wanting to do a cruise to nowhere to save your money, it is so not worth it.
As for the ship, it was small with very limited deck space and had few places for dancing.
