I had worked and volunteered with mobility impaired people in the past some using wheelchairs and walkers and I am familiar with the accessibility challenges some places pose for these individuals.While the San Jose Convention center is pretty accessible in terms of wide flat walkways, wide doorways, elevators, accessible toilets with wide entry and exit ways, and step free concourses there are still issues such as long ways to get around certain floors, steep ramps, etc and the issues you mentioned. One thing that bugs me is the city made the convention center less accessible after the renovation they did at 2013 such as destroying the wide accessible "curbless" passenger loading zone and adding steps to the front of the center just to make it look nicer on the outside. Now cars and city buses have to jostle for the curb space.
While I haven't gone with mobility impaired people to the convention center I am pretty familiar with this convention center's lay out as I had visited it quite often for different events including Fanime. I also stayed in hotels where there are large events that tie up the elevators and learned some tricks of the trade to beat the congestion. These tricks would greatly help mobility impaired and everyone else with the elevator girdlock which we all dread to face and can apply to most large events involving hotels. For example I learned the second level of a hotel is the worst place to wait for an elevator as the elevator will almost certain to be full in both directions and will often skip the floor all together. Fortunately at this Con we have a good alternative available nearby which are the three elevators in the convention concourse as those elevators only serves two or three floors max(not 17 floors)so it always empties out when it reaches the first or second main floors. The distance of those elevators are not too far from the Fairmont which is directly connected in the second level and having a power chair or electric scooter helps.
If you happen to be staying in the hotel itself and have trouble getting on an elevator to and from your room, the best way to get an elevator up to your room is to get to the lobby elevator landing floor(via the three convention elevators if necessary) where the elevator would release the descending passengers allowing you to get in afterwards with others going up. When heading down from your room floor, if the down elevator continues to arrive packed or wont stop the other option is to get on an "up" elevator and ride back down. If all possible I recommend requesting an accessible room on a higher floor which makes it much easier and many cases faster to get on a elevator down with plenty of room left to spare. From my past experience its nearly impossible to get on a down elevator from the lower 40% of the floors of a hotel at "rush" hours as the elevators become overloaded by then and either they will skip the floor or be too full to fit any more people.
Other tips I recommend for event goers is that the entrance from Market street is the easiest one to get in particularly if one cannot walk far as it is closest to where most activities are occurring and have no slopes or steps and one avoids most crowds that usually tie up the San Carlos main entrance which has a lot of obstacles and steps. The Almadon entrance has steps and a steep slope. As for Dealers hall and Artists Galley the best advice I have is to head early probably when the people line up to get in or go during the first weekday of the event. As for the game room the least crowded hours are 5-10 AM, its the best time to experience all those neat games without waiting for others to finish playing. Though I hope they make clear announcements before they change the entrance and exit patterns and post clear signs I can see this would be very difficult for people who are mobility impaired as the "entrance" and the "exit" is very far apart and a mistake would mean a 1/5 mile track. I Hope my advice helps.
