Jeph, the Fredericksburg Inn had some rooms available last time I checked.

No lodging in the area is cheap though, and this place is no exception... Fredericksburg is one of those hill country town where husbands spend far too much per night on lodging to keep their wives happy and every hotel, motel, inn and bed and breakfast house owner knows it.
Etna and I are staying there Saturday night, opting to shack up with relatives in New Braunfels Friday night to save some money.
