Christian room sharing ettiquite

In ye olde Christian days, males and females would not share rooms until they were married. whatever people think about sex before marriage (and for now that post has been and gone), I'm left wondering what the correct view is on sharing a room. Virtually all (if not exculsivly all) christian couples I know will share a hotel room on holidays, weekends away, weddings etc.

So, thats acceptable, but if you go away in a mixed group, and sharing a room with someone of the same gender becomes acceptable, people tend to do that instead. Does that mean its only acceptable to share a room with a boyf if there is no other option other than spending a fortune on 2 rooms? Or is that the done thing because people are worried others will judge them for room sharing when its not strictly necessary?

Meh, someone should write a manual on what to do about this stuff.

Incidentally, this is purely hypothetical at the moment. Me and the man have not stayed away in any hotels, or have any booked. Also, am quite happy sharing a room with him wherever. The exception of course might be with a group of people who dissaprove, who force us to share seperate rooms. Time will tell I guess.
