Copper Mountain only has one trail, but it swoops and switchbacks back and forth all the way down the mountain. It is very smooth so she will be able to focus on things like braking and turning techniques instead of the technical parts of the trail. My wife felt really comfortable there and had a much better ride the next time we went to Keystone.
I would vote for Copper, too. 2 or 3 trails criss-cross the front of the mountain so you can probably spend a morning or two. VERY light traffic on the trail, too. There's a couple decent pub/grill restaurants where the trail runs right into the main square. Standard burger and sandwich stuff, but decent variety.
We rented a condo from a sublet company last summer and stayed a week with my small daughters. For a first-class dinner, go to the CB (Covered Bridge) Grill. $20-$30 entrees, but I considered it a value for the quality you get.
If you have kids and are staying at the resort, there's free babysitting Thurs-Sat nights as long as you bring back $30 per kid in receipts from dinner or shopping.
The Colorado Trail traverses the mountain too, but if you take it to the west you end up slopping through about a mile of horse-damaged trails before reaching the pristine areas. Worth it for a long ride, but not for the weak of stomach.
Probably way more than you wanted to know. Good luck.
