alyeska is in my top five resorts, especially for april riding; killer views, decent in-bounds rock drops (christmas and new year's chutes are fun), cool loc-dogs in girdwood, fun cat tracks to spin off of...good times.
hatcher's pass is fun, also. well worth a cat shred trip for a day or two. we were taken to an area, i believe it was called 'goverment headwall', that had steeper terrain and decent slope aspects (wind lips, mini chutes, cliff bands, etc.).
once you ride in ak, it ruins you...nothing really compares to it (especially, if you get it on bluebird). i always find myself using ak as the litmus test against other places.
