He he, it's funny how perceptions can have no basis in reality, but I've always thought RCCL as a brand seemed just a little bit snooty, whereas Carnival has that, "Everyone's welcome, come aboard!" feel.
Mrs. Brown and I have been on 7 Carnival cruises (with 2 more booked!) and none on RCCL, so I have no basis to compare the two, but Kuki is asking for impressions, and that's mine. I don't even price other lines when planning cruises. Our first cruise in March 2002 (Inspiration from New Orleans) was so fantastic, just beyond our wildest expectations, that we never saw any reason to try another brand.
