Where to play in the winter?

Now that it's getting darker earlier, and with the daylight saving ending soon, it seems like playing tennis for people who can play weekdays after work is going to be hard.  There are only a few courts with lights, and they are almost always crowded.  What are my options?  Are there any good/cheap indoor courts around here?

Do people move to things like squash/racquetball during winter?

Looking for ideas!
