Now that he’s 51, Sean Penn doesn’t take any chances on drinking and driving. Or maybe he just drinks more. He likes to hang out at Sunset Tower in West Hollywood, which also happens to be Jennifer Aniston’s favorite bar. When Sean is planning to have a few cocktails there, he calls ahead and reserves a room just in case. If he happens to get too liquored up to drive, he stays overnight. And if he has a hard time finding his room – the staff helps him out – they like him there.
