First, the elevator situation was very unfortunate. Since this is the hotel trying to upgrade their ancient elevators it is a good thing. But I do wonder if the rumor that it will take two years to upgrade the elevators is correct, I do wonder why it is taking so long, and why the elevators in service are so fragile and slow that the backups become problematic. This is aggravated by the fact that, like many conventions, the hotel has more rooms than the con can occupy so there are a number of non-con members in the hotel who may not be nearly as understanding of elevator restrictions -- not that there weren't fen who felt it was unfair to have to wait for an elevator or not push to the front of the line.
Second, the ballroom area, which is more or less at a basement level, had almost no cellular coverage. This is a problem for people like robot_grrl and I who use our cell phones to communicate regularly during cons, and for merchants (including other cons and bids) who use cell phones to take credit cards. I suspect that this may also be a problem for other conventions and training events that make up the bulk of the hotel's weekday business (I doubt that three fannish cons are the only users of the function space at the hotel), so the hotel should probably work with the carriers to resolve the problem. Personally this was aggravated by the fact that T-Mobile seemed to have poor coverage around the hotel.
Finally, the restaurant guide for this year was completely useless if you didn't know the neighborhood addressing already (the map side had no marks even for the hotel) and the one from last year that showed up sometime on Saturday was only marginally better since it didn't have a good scale. It occurs to me (and I am NOT volunteering to head this up) that Loscon, Anime LA and Galifray One could share the effort to put up a restaurant guide wiki someplace where people could contribute reviews, distance information and updated lists which could be used to generate a guide shortly before the convention.
