I stayed at Kuredu earlier this year for a week, followed by a week on a Peter Hughes liveaboard. My strong suspicion is that you simply cannot go wrong. I've no real idea what atol Kuredu was on (you could check - they have their own webiste) but the place was stunning and the diving even more so. Literally at the sea in front of our beach cabin - would be juvenile reef sharks swimming up and down all day. They were so cute I can't do them justice. About a foot long! Just walking to the beech and snorkelling I saw; eagle rays, full size reef sharks (black tip), octopus turtle, huge stingrays, etc etc. Oh and large school of snapper - again just by swimming out by my beech hut.
The pics of the snapper are snorkelling pics - the others were diving.
Not sure if I've been too much help but the main thing is;
1/. you are going at a good time
2/. I honestly don't think there is a bad diving holiday in the Maldives!
