Zac Efron adjusted his shades as he headed out for an appointment in LA yesterday, and kept his eyes covered during a stop at the Sunset Towers hotel today. He arrived in town earlier this week, and wasted no time getting back to his social routine — attending a bash thrown by Nylon Guys in his honor last night along with Ashley Tisdale. It was the latest meetup for the High School Musical friends, who are spending some quality time together while his girlfriend and her BFF Vanessa Hudgens is off working on her new movie, Sucker Punch.
