I live in the Middle East. 10 hour flight to Tokyo, 15 hour flight to Seattle.
I've been to the Alps once this year and am going again in March so I'm not looking at Europe for April. I've also got the same issue in 2013 since the trip is with my son and his school holiday falls in the early April this year and next year. I'd prefer to go somewhere I've never been (Japan, Canada or Utah). I've skied most of Colorado, Jackson Hole and Tahoe.
My recollection of Colorado is that snow is iffy everywhere in April except A-basin.
