Check my trip report from last Monday for a list of the features - it has probably not changed much since then.  Unfortunately, they will not let you ride up the Mile Skyride with skis, so you would either have to hike to the Palmer or find someone with a pass to carry your skis up the lift.  My brother and I hiked to the Palmer all summer, and it is not a bad walk - I would guess it will take somewhere between 45 minutes and an hour to walk up the paved path to the Silcox hut - which is right by the park on the lower Palmer.
Powder-weasel and I will be there doing our old guy gaping the park routine tomorrow - hit us up if you come to ride.
