They have BINGO markers that are tubes of ink with a sponge tip- there are many colors. I think a mug and gourmet beverages would be nice (Starbuck's has those VIA instant coffee singles that are pretty tasty if she likes coffee), or you could put gourmet tea or hot chocolate. I read an idea at Frugal Family Fun blog to make tea bag tags out of kids' pictures- very cute! Maybe get a lap blanket or scarf or fingerless mittens. Travel sized lotion or hand sanitizers would fill the space, too, and maybe some sort of "good luck charm".
