Thanks Burbunny for confirming that the Spirit does not have the two bedroom suite - it's good to know. Those suites are a boon for families, as most NCL suites will not accommodate more than 2.
lg10, just be aware that there are mixed feelings about NCL's quality when compared to some other brands - and it's all an issue of how much you spend up front vs on board. Food quality is a big cause of contention - the Freestyle dining concept offers a lot of dining options, many of which have additional fees. People will often make direct comparisons between lines based on the main dining room experience (included in your fare), and NCL often falls short. But then the cruise itself is often much cheaper, so it's not a fair comparison. My experience on NCL has me add in the extra cost of dining in "specialty restaurants" (fantastic BTW) for at least every other night of the cruise, plus the extra cost for a suite (I am spoiled) to make it comparable to much, much higher priced lines. I have sailed suites on Celebrity, Carnival, and RCCL, and the NCL suites do really knock those other out of the water, so to speak. The main dining rooms are good, but the specialties are great. People often complain about the cost of drinks in the bars - but NCL's prices are the same as every other line.
So, in Flyertalk Speak, the people who do the most complaining about NCL are looking for a Hyatt at the price of a Comfort Inn, if that makes sense. You pay for a Comfort Inn, that's what you get. NCL can be more comparable to a Ritz Carlton if you are staying in a suite and eating at specialty restaurants, at the price of a Hyatt. Hope that makes sense!
