The 8am bus run by Pullman by full and we took the next bus at 9am run by Bus Sur (CLP 4000/person, about US$8) which dropped us in Puerto Natales at noon. We stayed at Hostal Lili Patagonicos which was my favourite hostel along with Elefante Rosa in Buenos Aires. It had nice cosy rooms for CLP 18,000 (US$36/night) with wi-fi, TV having quite a few English channels and the yummiest comforters imaginable that just made you want to curl up in bed and not get out. Lili Patagonicos also had an attached travel agency from where you could book bus tickets to Torres Del Paine National Park and other day trips such as the boat ride to Serrano & Balmaceda glaciers, Perito Moreno glacier in Argentina etc. Ivan, one of the owners, was extremely helpful and guided us on some of the trails that we should do and how we should structure the days.
