The guy who invented this whole business thought these little things mattered, and to this day, the theme parks that sprang forth from his mind still rule the theme park world. A little story:
Legendary Imagineer John Hench once complained to Walt about attention to "unnecessary" details. There used to be stage coaches in Frontierland that had leather suspension straps. Hench felt there was no need for this, as they were harder to maintain than more modern technologies and that nobody was going to notice anyway. He proceeded to get a lecture from Walt about how people actually do care very much for these kinds of details, even if they don't consciously know it.
The cumulative effect of ignoring these little things...of making these little changes...is that the park becomes a place for people to use for entertainment, rather than a place people long to visit and escape to. When you take the time to build the carriages with leather suspension systems, like they did in the old west, people get the impression that the place is built with some heart, and with some care, and that it's not some dirty sandbox to go trash and throw away like a disposable amusement.
Disney understood that every little thing matters, from the napkin rings to the ticket stubs, and when you have a major park attraction, you ought to treat it like it matters, or otherwise the audience won't.
Every little detail is an important one. Terribly important. If you want the audience to care about what you're trying to do, you sure as hell better give the impression that YOU care about what you're doing, and never give them the slightest hint that you have looked something over or are trying to save a buck. They need to feel that this place was built for them to visit and escape to, not for them to slouch around in and kill a few hours. You ought to forget there's a world outside of Busch Gardens when you're at Busch Gardens, and the park achieves that effect by caring about these kinds of details.
