We have stayed at the GCH every time we are there since it was built. The issue is a bit different for us, we were in DH in 1994 when the northridge earthquake happened. 8th floor in the Bonita tower, which was the only one closed afterwards. My wife will not stay in the DH since. The first time we were at the GCH there was a business man up on the top floor looking at all the beams. We got talking to him, and his company did all the fiberglass covers for the steel beams that make it look like wood. Really interesting guy to talk to and a nice tidbit of info that Disney does not talk about. If you get a chance, go to the top floor and look at them.
