If you & your girl friend are about equal in ability and really good - then Whiteface is a Great Mountain. The fundamental problem is that there is very little intermediate terrain that is easily available - I.E. you will have ski or board on some very hairy stuff to get to or get out of much of the moderate terrain.
Most of the trails have compound fall-lines (side-hills) and the bulk of the vertical happens in the top half - from there down is a long flat run-out.
For example a Blue Square run at Whiteface is a Black Diamond at Stratton is a Double Black Diamond at Flat-Kemo (slight exaggeration) but not much.
I, too grew, up dividing my time between Vail, the "Tilted Rink" (Whiteface) and Lake Placid for soft-water skiing...
But, IF you put in a solid winter at Whiteface and you will be competent to ski anywhere and in all conditions. Even out West - IF, there is enough snow to gain mountaineering experience in the "Slides" which as the name implies is what the snow does over there.
And then there are all of the 1932 & 80 Olympic facilities including one of the few Bobsled runs in North America.
If you want less of a challenge? Then I would suggest Jay Peak (often has much better snow -different weather pattern), Stratton, Killington or Sunday River. If you don't want to head that far north try Windham Mountain in the Catskills surprisingly good terrain for a small area.
And then there is Colorado or Utah - Snowbird and Aspen Mountain are among my faves.
For snow and lots of it - Mammoth Mountain is hard to beat - 226" so far this year. It is like driving around NY City but instead of granite buildings you have 2 or 3 story snow banks that you can not see around at the intersections...
