Do you have warm clothes? It will likely be windy and cold in November, and you should have winter gear if you venture out of town. The car rental agencies don't seem to put winter tires on their vehicles (or maybe it's just the cheap cars that I rent, but I've had some scary experiences slipping and sliding on Anchorage roads -- and I have years of experience with winter driving).
Driving to Girdwood (Alyeska) should be okay since it's a well traveled route. If you are going primarily for the tram, check to make sure it has reopened for the winter:

Whatever you decide, keep your plans flexible in case there is a big snowfall or frigid temperatures or icy roads. But the weather and road conditions may be just fine.
