Tahoe is a good option. There are shuttles to Kirkwood and other mountains that make it work the effort. Generally not as effing cold as Vail......esp mid-Feb. Some Tahoe places (excluding Heavenly) get much more snow than Vail.
SLC is really spread-out, so I don't think it'll be fun for the ladies.....Park City is a much better centralized option with plenty to do for all. Don't let the mormons scare you, there is plenty of fun to be had in Park City!
Vail is a good option, but can get silly crowded. If you drive somewhere else, I suggest heading up to Steamboat over Breck. Breck is decent, but needs a good snowfall/base for it to be really good. Steamboat just gets blasted with snow and not nearly as many people as Breck. Breck gets beat-up by the crowds. If you've never been to breck, then you should go, but I wouldn't put it atop the priority list.
