I live about 20 minutes from DL and often visit there by myself. I think you'll feel very comfortable there by yourself. Since it is much smaller than WDW, you won't have to worry about busses, and travelling around a resort by yourself. You'll be able to walk everywhere.
You'll have many restaurants to choose from there, shopping, and movies. If you feel the need to venture out a bit, you can take a cab to The Block At Orange. It's about 10 minutes away (all surface streets) and is a large outdoor shopping, entertainment area.
