I suddenly decided to go to the Expo on September 14th, and this is the guidebook I bought. It includes insider tips on how to enjoy the Expo even if you can't get into the pavilions, so it will definitely be helpful for those rushing to go. It comes with a large map, approximately 43cm x 30cm. To keep it clean, I've put it in an A3 clear file, and I will send it in that condition.
