Yeah the general wear and tear starts to become very noticeable in the later weeks. To me the prime time to see houses is in the 2nd or 3rd week. At this point they've usually gotten whatever improvements they might be getting and generally not too much has been taken away or worn out yet.
My take is it was worth the money. After experiencing it $50 is a lot for what your getting. I can see the value in what they put into it though, but spending $50 for a 15 minute experience can be hard to swallow for some. I don't regret doing it, I will do it again next year.
