CF, there are two of them living on ships now. One on Princess and on on Cunard. I have a gentleman who although he doesn't live full time, he might as well. I just booked his 83rd cruise. He at least goes home for a couple of weeks at a time in between. He's also not line loyal like the two ladies. About half are with RCCL or Celebrity but he books anything that looks interesting to him. Just an FYI, he said his all time favorite was new years eve in the orient.
