As for the Barnes and Nobles...I'd seen it online that it had an available date of March 2006, but when I was in the actual store the clerk couldn't even locate it in the computer...I'd even given her the exact name...so I knew it was behind schedule for sure. I'm hoping it comes out just in time for Mother's Day...it'd be a nice gift right before our trip! I bought the Unofficial Guide, which is good for someone who's never been to DL (me), but I really love Passporters...they just seem to have more detail though.
I'm not so patiently waiting for the DL guide to be published!
