K.,
As far as family activities that are a bit different, how about:
1) Stockyards/Rodeo
2) Midieval Times
3) Dallas World Aquarium
4) Glen Rose, TX (about an hour and a half away) A safari!! If you haven't been, you have to do this! You stay in your car and drive around and the animals come right up to your car and the giraffes stick their head right into your car!
5) Southfork
6) Waterparks
7) Studio Movie Grill - you can have a mommy/daughter night out and eat dinner while watching a movie.
As far as a care package:
1) Her favorite magazines
2) Gift certificates to her college's local restaurants
3) A few family pictures for her to hang in her room
4) If you want to get nicer and if she doesn't have these things, perhaps a camera and a cell phone (although I'm sure she has a cell phone)
5) Soduku (if she is into that)
6) Board games, like Taboo, Scattegories, etc. - fun games that she can play with her new college friends
Hope this helps!
