I would offer an ereader and nothing else. Because I think that 2 weeks of vacation time (I am assuming vacation) is tolerable without books. I usually take an ipad with ebooks loaded, a sudoku book (difficult level), a puzzle book, chess strategy puzzles, a soroban math book and one really big classic literature book (like Hobbit, Narnia etc) to read aloud to him and that keeps both DS and me busy
He also brings his journal and writes about his trip and draws pictures when he is bored sitting around and does not want to read books on his ipad.
Lol, I personally would go crazy without access to books for two weeks!
We have a similar routine for our longer, international vacations. For example, we're going to Italy for 3 weeks. I will load both my Kindle and iPad with ebooks (so two people don't have to share one reader!). For DD6 I will also bring along some math word problems, a journal for writing, a small activity unit on Renaissance artists (to supplement what she learned at school this year), and a few easy to pack trivia games.
My DD also gets carsick and can't read in the car. That is where audiobooks are a lifesaver. Charlotte's web and mr poppers penguins Are two favorites in our house. She also listens to a lot of music (but music is her passion, and might not be as entertaining to others!) in the car.
