One of us would have to go...
I'm series. I'd get her a hotel room. That's really what your dad should do.
My brother brought his girlfriend and another couple to visit me when I lived in an apartment in Austin. I moved in with a friend and let them have the whole apartment to themselves! We hung around (a bit) during the day...but mostly they were just there for a good time in Austin and I left them alone...
My brother could afford to do that. But he has his views on what's the best way to introduce her to us.
I'm kinda worried that she's going to be able to TELL we've already been arguing about this and that I really don't want her at my place.
Ben is just SURE that we're going to be best friends (especially as she's closer to my age than to his)...and I think that's one reason he's trying to force the issue. It's not the best way.
