We were in New York for the weekend to attend to some wedding (my wife's side) We stayed at the Alogonquin, and I got a pleasant surprise to find Kindles in our room, which was preloaded with, FREAKONOMICS, which is my favorite book at the moment (still rereading it, after 10 re-reads)!
This is one great way to surprise your guest! Other hotels should follow their footsteps and innovation!
