Hey, guys, you've probably already booked, but here's my two cents' worth, just in case. My company books small gay groups on "mainstream" cruise lines, and the two lines we use more than any other are Princess and NCL. Obviously they're both extremely gay-friendly, or we wouldn't use them. Princess is certainly more upscale, and thus attracts a slightly older demographic. BUT longer itineraries tend to skew older, as well, so there probably won't be too much age difference between these two sailings. Which is likely to have more gay guys onboard? That's a total flip of the coin, though NCL's well publicized FOD meetings might make it easier to spot the like-minded guys. And it's completely unfair to compare an NCL cruise in Hawaii with one in the Caribbean. The Hawaiian fleet is a totally different division of the company, and it's greatly hampered by American labor laws. (Sorry, but spoiled American kids just DON'T make good cabin stewards, waiters, etc.)
Still, here's my bottom line: I'd do the Princess cruise. You'll find that 10 days in the islands is enough, and then you'll have time to spend a few nights in Miami/Ft Lauderdale, where you're BOUND to have a gay old time. It's just too bad you can't sail with us on Oct. 28 ... I LOVE Kiwis
