I wonder where they stayed? I sometimes go to Salt Lake around Sundance time because my older brother lives there and his birthday almost always coincides with the festival. All the hotels by the Temple are jam-packed with festival goers and you can play a great game of Spot The Celebrity. In the past I've stayed at the Marriott and Little America. Since Her appearance was supposedly unexpected (c'mon, it's a prestigious fil festival. Of course She'd be there), I imagine They had to scramble for accommodation.
