Honestly, I feel that Lylat Cruise is a far better stage than Yoshi's Island. The ledges on YI just scream for PKT ledge bouncing. I don't see the support ghost as too much of a problem since you can recover from the spot it appears on. And as for shy guys, those are evil. Recovering low is also near-impossible due to a possible wallbounce. The stage itself doesn't offer Ness many advantages, either. It's a bad stage.
Lylat Cruise doesn't offer a comfortable recovery, but if you are used to it, it isn't too bad. The only thing to be careful on is when you are offstage. The stage itself is randomly tilting, but it doesn't affect your aerials too much. IMO, PKT does a far better job in the mindgame department here. The stage tilts and the thunder can get too erratic to respond accordingly.
Most people hate both of these stages. IMO the only one to hate is Yoshi's Island.
EDIT: I am one of those people that stay up late. 30 minutes - 1 1/2 hours of sleep is just too little, though.
