I see NCL is running a 40% off sale, and it appears it was just extended a few days. Anyway, my question, are the prices listed particularly good? As in, unusually good? We're looking at taking a cruise in June or July, but aren't yet sure exactly what we want. We're leaning towards Caribbean, but we're not sure. I've heard a lot of good deals usually come late winter or early spring ("Wave season"?), and since we're not really yet ready to book I'm wondering if I'm likely to miss out on a good price if I wait too long or if this is one of those "revolving sales".
