Okay I got a minute. Assuming you have a car, you might look at Idaho Springs for cheap lodging. That will put you about 30 minutes more or less away from A-Basin, you might make Loveland in 20. You can buy discount tickets at the Safeway in Idaho Springs. It's easy to find as it's on the main drag there. Also Tommy Knockers and Beau Jo's Pizza are great places to eat and drink. Pretty much a mountain kook town, but you will find some shops there for snowboard gear etc.
The major problems with this, is on weekends you are traveling with Denver traffic. So you'll have to fight with me and 100,000 others heading up the hill and back. Second, if the storms go huge (dumping feet) I70 can get closed at Georgetown. If that's closed you can bet Berthoud Pass is closed. Then you are hosed. I guess you could go to Echo Mountain, maybe Eldora. Those would probably be the only options to get resort turns. Even backcountry is super limited when this happens.
I think the prices tend to go around $60 a night in Idaho Springs and up from there. Most places are pretty much old motels, of the fleabag variety, but I am sure they are serviceable. They've been there forever so they can't be that bad.
If you can find a deal in Summit, if the roads closed and you are there you're fine. No crowds at the resorts, what's wrong with that? That would give you the option of hitting A-Basin, Breck, Keystone, or Copper. If the roads close, Loveland is definitely out as an option. Keep in mind road closures don't happen often. I've seen several seasons go by without a weather related closure. When they do though it can be days depending on the strength of the storm.
