I can't help but to recommend PASSPORTER. The info is as good as Birnbaum but there is so much more. Great maps, great tips, and Jennifer and Dave are REAL people and come across as such. Isn't poor Birnbaum dead?
I always get Birnbaum but Passporter has places to write in and nifty pockets to store receipts, maps, confirmations, tickets, etc. I used mine a lot this last trip. There is also a great website with updates and boards to talk to other FANatics. I got mine at Borders bookstore and you can also order online right from Jen and Dave (Passporter.com?)
I am going to get a new Birnbaum soon AND the new Passporter as soon as it is out!
