Query: Give me PassPorter 2000!

This book is great! It's hard to believe that the authors could have improved on the original, but they have. There are more pockets, for longer vacations, more and longer restaurant reviews, more tips and a sturdier book altogether. The maps are larger and more detailed. It makes planning a vacation at WDW a breeze! And it's still at the same price! Thanks guys, this is just what we needed for our next trip to WDW!
