In the first his naked leg and bare arm were just swinging into the frame. In the second, he was nodding to a smiling bellhop who had pulled the door open for him. The man was probably in his early forties, tall, slender, blond hair with bald patch, wearing a skimpy pair of loose shorts and a haggard tank-top shirt emblazoned with the logo of a triathlon. Track shoes completed the ensemble. Strapped around his waist was a fanny pack, with a water bottle holstered in a black mesh pocket.
