I think it is more meaningful... If I just found out (as a 21 year old) that when I was 4 and my parents were at WDW without me, they took the time to go and meet characters and get autographs for me because that's what I wanted, I would think that's very thoughtful of them. If they told me ,"Yea so you wanted autographs, so we just bought the book and signed them ourselves cause they're not real and you'd never know anyways..." I'd be kind of disappointed, not because the characters are not real, but just because the process of them getting the signatures seems more thoughtful to me. I mean, if wouldn't be a big deal either way, that's just an example of what I meant.
