Do they also have YouTube blocked? My daughter and I were in during December, and we passed a lot of time culling YouTube for funny clips to email to her cousins. Then they started to email links back, and it was a nice way for them to all stay in touch without having to really say much (since, really, not much worth talking about was happening!)
As odd as it sounds, we also had a blast with MadLibs. We would ask the nurses for words, then they would want to stick around and hear the final result. A bit silly, but after the third day, silly at least passed the time!
