I gotta put in a plug for Pleasant Mountain (FKA Shawnee Peak). It's a little farther from you than Lost Valley, but there's a little more room to move around and there are a few great snowboard instructors who often do family lessons.

But the best answer is whichever place is most convenient and that you'll actually go to regularly. If you want to snowboard, you need to get out there and do it and develop the muscle memory and confidence to enjoy it.

Pleasant and Lost Valley are particularly good because they offer night skiing, which can be more convenient and less expensive. Monday nights at Pleasant are only $24 and there's a ton of terrain open under the lights.
