We aren't going until March of next year (fairly late in the month). This looks like a great book, but I think I'll wait till January of 2011 to order as they may have Harry Potter stuff in by then.
FYI: I have the book "Beyond Disney, the unofficial guide to Universal Orlando, SeaWorld, and the Best of Central Florida". It's OK and better than nothing, but not anywhere near as good as the "Unofficial Guide to Walt Disney World". Thanks for the post. I'll be looking forward to reading the other book mentioned.
