Hi, my family and I (4) are thinking of staying in Puerto Natales for 3 nights as a base for Torres del Paine. I was wondering if anyone has done with a tour company a day trek to The Towers. I thought it might be more economical to stay in Puerto than actually in TDP. I also wouldn't mind on another day doing a bus tour of the drive and out to TDP with scenery stops along the way. Any suggestions would be greatly appreciated.
