Beginner's generally do not like powder because they are learning to link turns, and linking turns on a groomer follows a completely different method then it does on powder. In order to ride powder, you need to be able to link both frontside and backside turns, or else your just going to be falling, getting stuck, and becoming very frustrated.
When riding powder, the biggest thing to keep in mind is that it's like surfing. The more you try and stick in your edges and make short quick turns, the more your going to flail and fall. Riding powder is all about leaning back, getting enough speed and making smooth slow turns. The easiest way to experience powder in your situation, is on the side of groomed runs. What happens is that more often then not they don't groom the whole trail, so the sides will be normal powder, and the middle will be groomed. Just kick off the groomed run to get the powder, that way when you get frustrated your not stuck in the trees blowing a fuse.
GOLDEN advice right there.
