Disneyland is looking pretty spiff now. They seem to be using some sort of varnish over everything. The Castle practically looks plastic as does the Haunted Mansion. I assume this is the result of experience in durable finishes. Now I'm wondering, with all this new technology, why are there far more bulbs burned out around the park than I remember as a kid? During one of my early childhood trips I ran up and down Mainstreet looking for a burned out bulb and could find not one. I just assumed they monitored the current draw on each circuit to alert them to a bulb failure. Recently, however, I've been seeing plenty of burned out bulbs all over the park. One might think imagineering could do some research and switch to LED or other much longer life bulbs and also monitor the power draw so they'll know when something goes.
Does anyone know what they do to make things last and keep looking good? I certainly hope they are building stuff to last so they won't need to spend all their money on maintence instead of new Z-Ticket rides (E-Ticket rides are soo 1959).
