I'm actually not sure. The Ice Kingdom is beautiful, and it has ACTUAL SNOW, WHICH I ABSOLUTELY LOVE! But the dragons are strict, and I don't do well with strictness. The Rainforest Kingdom is equally beautiful, with incredible wildlife and plenty of resources, but it's SO HOT, and STICKY and HUMID with MUD and BUGS. Basically my hometown, but worse. The Sea Kingdom is spectacular, with interesting wildlife and a no-eating-dolphins policy, and I love swimming and the ocean, but the queen is a bit... well, Queen Coral's a great queen, but not a very good mother who doesn't care much for her soldiers. The Mud Kingdom is the same as the Rainforest Kingdom for me. The Sand Kingdom is just no all the way. Horribly hot with harsh conditions? No thanks. Not to mention the sand. I don't like sand, it's rough and coarse and irritating and it gets everywhere. The NightWing island is just plain awful. Volcanoes are scary, it's hot, there's no prey or water, and the beds are uncomfortable. The Lost City of Night actually sounds pretty nice, with decent weather, advanced technology, and a nocturnal schedule. And Darkstalker rules it. The Sky Kingdom is also pretty nice, with nice weather, cool wildlife, and a kind queen. So, to put it shortly, I'd have to go with the Ice Kingdom, Sea Kingdom, Lost City of Night, or Sky Kingdom.
