In Switzerland, Verbier is awesome for backcountry, not really park, but that time last year there wasn't a lot open. that said, there is more snow already than last year. May well be better off heading to somewhere glacial like Zermatt or Saas Fee where there should at least be a good park. As you say, Les diablarets could be a good option for the park.
