I'd like to see an electronic version for the iPod Touch/iPhone as I'd be carrying it anyway. There are a few good book readers for this platform and a lot of travel books have started publishing ebooks.
I've been twice to WDW in Florida and bought the book, I didn't know there was a Paris one - must check it out. My DD is 4 and DS will be 3 when we're there and I've spent ages on the Disney website's trying to work out what they can go on so a minimum height for each ride would be good if it's not already there.
O/T but the 50's diner was my favourite tip from the Florida book - we were in Florida in 2001 during the attacks and went to the diner a few days after in the middle of a tropical storm, it was a nice step back in time that made you forget what was happening.
