I pretty much agreeHit Alpine ($39) & Squaw (my fave) & on Thurs/Friday; Kirkwood on Sunday & Mt. Rose on Monday (assuming you're flying out of Reno). If you must ski Heavenly, ski it on Thursday or Monday and only on a bluebird day.
Here's a gameplan for Squaw that I'm reposting (it's not a big secret), with some additions for a whole day/couples:
...this is an efficient way to survey the mountain & ski, instead of spending time traveling around. Look at the map online before you try to do this...
If you have skis, then park in the lot between the old Red Dog Grill & Far East lift; there's a ticket kiosk right there & you can park within steps of lift. Take Far East chair up.
[If you don't have skis & rent demos from Squaw Ski Shop, then start at KT-22.]
Go down Red Dog/Dog Leg to KT-22. Take runs off KT-22, including Oly Lady side. You can see a zillion lines; some expert, some advanced, some psycho.
[If you're more conservative/intermediate, there's a groomer off the back of KT down to Headwall]
From KT-22, ski down Rock Garden & hit Headwall Chair. Ski the Nose & check out both sides.
Next time up, take trail around to top of old Cornice II & hit chutes below ridge there (really, they're not that hard). If you're up for it, you can turn & take a left & hit the Slot before you get down to the top of Cornice II.
After a few laps, go straight off the back of Headwall into Siberia Bowl. Take Siberia lift up & ski Siberia Bowl to Gold Coast before 11:30.
The foregoing will take you a couple of hours.
Gold Coast Bar is in lower level of the building, and there are outside tables with a decent view of Headwall, KT, etc. The bar is steps from where you can ski up. 10 minutes later, walk up about 50' to upper level of building (where Funitel exits), put on skis & skate/pole over to Emigrant Chair.
From Emigrant, drop down the Funnel & ski down to Granite Chief Chair. Take a run on Granite Chief & take Shirley Lake chair up. [Intermediates can simply ski around & hit a groomer off backside Emigrant, or frontside, with a sharp left to take Shirley Lake groomers.]
From Shirley Lake chair, head down to Silverado. Take Silverado up/down/up.
Ski down Mountain Run to Red Dog. Take up Red Dog. Ski down Squaw Creek [there are 3-4 nice grromers] & have lunch at The Resort at Squaw Creek after 1:30. Have your wife get the child's burger, it's big enough.
Take Squaw Creek up. Repeat.
apre: Balboa/Le Chamois/Plaza Bar
also: Mamasake sushi.
Usually, the following applies:
Repeat as necessary.
Northstar: Never on a weekend (crowds), and not the greatest for level 8-9s. Decent groomers backside.
Mt. Rose: Great for a day; higher, so snow stays a little better. Some good steeps in the Chutes, some nice steep groomers on front/backside.
