IME (as an American) Korea is far more enjoyable if you know people there who can show you around.

One could say the same thing about any foreign country, but for some reason Korea stands out from the crowd.

Other thoughts:
-August is nicer than July IMO
-She should get a condo on the beach for at least a few days
-A car would be useful outside of Seoul
-Most Korean TAs in Los Angeles will let you add on a side trip to Cheju for $100 or so; well worth it
