Hey, I'm not Josh. But here's what we say in the book nowadays about crowd calendars (p114):
"We used to offer daily advice about six-and-a-half months ahead,but Disney has so limited the information it publishes that far in advance hat we can no longer be precise in this advice. For imprecise guidance for your dates, leave a comment on any page of Dave’s yourfirstvisit.net, or create a thread in Josh’s forums at easywdw.com/forums/forum.php."
To make sure you get other updates to the book (we have not done one yet), send me an email at firstname.lastname@example.org and I'll make sure you are on the list!!
