Okay, I realize that the use of the word "etiquette" is lame but nevertheless here's the question: Say you've got a girl who you believe has a high IL and you haven't done anything physical yet but you have known each other for some time. You ask her if she'd like to drive up the coast for the weekend and she agrees e.g. "I'm driving up the coast this weekend, wanna come with?" How do you handle hotel arrangements? Do you book two rooms? Do you discuss it beforehand?
