I just ordered the deluxe passporter for £19 from Amazon, which I topped up with a couple of letterland books for my eldest, to take the order up to the £25 free delivery price.
Books and guides are funny things....even though i've been 6 times now, and figure I know it all now, I still cant help buying them.
I got a Florida book in WHSmiths the other day, one I'd not seen before, but the Discovery Channel, and it really was excellent....not quite as detailed as my favorite brits guide (it didnt even, for example, have any height restriction details!), but it had better pictures, and a really interesting Florida history section at the beginning.
