Now we are getting somewhere.
Loveland is closest and cheapest and has a ton of above treeline skiing and sounds like a match to your ability level. Steep, but not overwhelming.
A-Basin. Though they are getting a ton of snow there this season, it takes a ton of snow to open. You MIGHT be able to drive over US 6 from Denver direct (over the pass) but might not be able to depending on weather in which case you would need to approach from the Dillon / Silverthorne area making it a fairly long drive. Far more difficult terrain than Loveland but an easy area to navigate as it is somewhat small with consistent terrain. There is plenty of fun stuff there, you can't get tired of the place and you can (for the most part) find the terrain you want to ski by just looking from the base and the lifts.
Keystone-skip it. It doesn't provide the "Colorado feel"
Breck. If the weather is bad the day you are skiing you may want to skip Breck, if not it's a good choice (bet none of you here ever thought you'd hear that from me eh?). You can stay in the high alpine bowls and chair 6 which fits your ability. There would be no reason to leave those areas unless E-lift was open. From your self described ability level a few runs would work under E-lift, but that area may beat you up a bit.
Copper is well within striking distance for the day. The mountain has naturally divided terrain, some above treeline type skiing and considered a "skiers mountain" The beauty is that you can pick an area of that mountain and stay there not wasting your time trying to "find the terrain" you really want to ski. It's a good possibility.
Vail The place is huge. You would really need to do your homework to find and stay on the terrain you want to ski. Plan a lot of time from the time you park the car to the time you hit the lift too. It's a walking / shuttle line village and it always eats time getting to the hill. If you want to ski the bowls you can head there and stay there for the day hitting Blue Sky in the process. BUT know your route in advance or you will get lost and loose valuable ski time. THAT IS IF THE BOWLS are fully open. Vail schedules the full operation of the back bowls and Blue Sky based on the calendar and not the snowfall. The BIG plus is that the 10th is usually the target day and it's a Friday. There is an excellent chance you could be there when the rope drops. I know a small area is open now, I'm talking about the GRAND OPENING. I would carefully watch the web site for the projected opening day which they always announce. IF it is the case that they are opening the bowls
on your ski day, it makes Vail the no-brainer if you like powder and wide open bump free bowls with a few small cliffs to huck off if you need a thrill.
I wouldn't consider any other places except Winter Park / Mary Jane and it's been so long since I've been there I can't tell you anything about them.
Watch the reports. Snowfall amounts can be fickle there.
Watch the terrain and grooming reports terrain will be in the process of opening. Those reports could make the difference of a good day and a huge day.
There may be better hotel values in Silverthorne / Dillon than Frisco. Do your homework there.
Terrain will NOT be fully open (but plenty for one day no matter where you go) so watch the scheduled openings
It's about an hour and a half from DIA to the Silverthorne / Dillon / Frisco area if the roads are dry (you may make Vail in 1:30 if you are a diplomat with immunity and the rental car is a Porsche.
Have a blast and let us know how it goes.
