I have to admit that I was one of those people who hardly prepared on our first trip. Ah, I remember it well. Dumbo, (uncovered at the time and out in the scorching heat), with a horrible wait of 1 hour. I did read Birnbaum's - but it wasn't very helpful to me (and there was no internet in my house).
THese boards, together with the Unofficial Guide, are a tremendous help.
Oh, and you'll still see the people that walk into the parks and say "ok, what do we do now"!!
Have a wonderful honeymoon.
