We had a lovely ski vacation in Ischgl late March. There are many red and black trails that stay open until relatively late in the season. I recommend this site for intermediate/advanced skiers. It is pretty easy to ski between different areas if you can do the reds and blacks. However, because it is among the more expensive ski sites, it is a waste of money for someone who is just starting out and won't be able to benefit from the higher slopes. Better to go to Bulgaria or even Italy where the whole deal is cheaper.
One of our favorite experiences this trip was going night skiing. It was really special and highly recommend it! I can't say that I was impressed by the Austrain cuisine or by the locals. They are cold as the weather and enjoy nothing more than eating pig three times a day without giving a thought to salad. It may be in my head, but I think I picked up on some anti-semitism as well.
