Cruisin'

We're thinking that maybe it's time to try a cruise instead of a resort for vacation at the end of May. Any experiences to relate, good or bad, with specific cruise lines or packagers? Especially, comments on the food and the noise/chaos level. :) Other cruising advice? (I've already read Ian's message from this spring.)

ETA: when I say "noise/chaos" I'm thinking of all types, from young exuberant children, to packs of mall-rat teens, to geezers who think that 6 a.m. is "sleeping in." It's not (just) about young kids. :)
