Hi folks - good to hear the new edition is finally getting out there. We had our doubts, with the postal strike and all! As strange as it may seem, we have only just got our authors' copy out here in the US and it had been absolutely soaked through at some point in the postal system, so the first 100 pages are completely unreadable
We should get some more soon, though (we hope!).
Just to underline what Deb said earlier, parts of the book will be pretty much the same as 2009's in areas like hotels and shopping as not much has changed in the past 12 months or so. But ALL the copy has been reviewed and checked (and refreshed in places), while there are new sections on all the latest attractions (Rip Ride Rockit, Manta, American Idol Live, etc) and a whole new preview section on the Harry Potter development at IoA.
As regards the Brit Guide and the excellent Unofficial Guide, we always say that the UG goes into greater detail as their focus is primarily WDW, while we try to provide a fuller overview of the whole of the Orlando area, to the extent of providing a chapter on two-centre holidays to the likes of the Gulf Coast, Miami and Florida Keys. If you can get both, you should have the perfect companions to the complete Orlando experience
