Watch out for misplaced trees from the forward tees! I played TR with my then girlfriend, now wife back in '99. It was her first time on an 18 hole golf course - and still the only round she's played. Not bad for a one time golfer. Anyway, I played the first 4 holes with her from the front, and two times was stymied by trees - one time from overhead on the 3rd tee, the next time on the 4th tee, there was a tree right in the line of the drive (I've been told it has since been removed).
I don't know what tees your girlfriend is playing, but she probably doesn't need to go all the way up if she can carry the ball at all.
