I guess I'm the first one to post about the new location, being at the Fairmont Hotel, inside the Imperial Ballroom.
This is just my thoughts on the location, hours, etc. Not trying to cause drama. And sorry for being a little long 
I will say that the Fairmont hotel is kinda out of the way from the convention, not "across the street" like originally planned, making travel to/from the convention center with your Swap Meet items even more a hassle to carry/transport. The Fairmont does have parking as you stated, but that's more of a hassle for me since my car will be parked inside the SJCC parking garage, and leaving it to drive to the Fairmont would be mean giving up a good spot and paying one fee, and I don't know if the Fairmont also charges for their parking lot.
The main issue that people will have with the Swap Meet being at the Fairmont is foot-traffic. With a lot of events and people mainly at the convention center (Friday mainly), the majority of people will want to remain there and not go out-of-their-way. Last year I went to the Fairmont only once to find friends, and I had to ask friends how to get there exactly since I never went there before as-long as Fanime's been at the SJCC. With the Swap Meet being inside EH3, where the video-games are, it brought in a lot of people on both nights.
Set-up time is 6:00-8:00pm, and the event opens at 8:00pm. So that means if Seller #1 checks-in and sets up his/her booth at say, 6:10pm, he/she can't sell anything until 8:00pm when the room opens? Previous years with the Swap Meet being inside EH3, people would be able to walk-around and look at what Sellers were offering. (True, we weren't technically allowed to sell stuff until the staff said it was okay) but this year that's a loooong time for the first group of sellers to wait before the public can look/buy their stuff.
The Swap Meet goes from 8:00pm-11:00pm on Thursday, and 7:00-11:00pm on Friday. I can understand since it's inside the Fairmont this year, the hotel probably wants the room closed by midnight the latest, but that's earlier than previous years where we could sell stuff until 12:00 or 1:00am. For myself, I usually shut down around midnight, but for those who really like to stay until the very end (1:00am) they won't be happy with the 11:00pm closing-time.
What also is tough is for those who have the higher #'s (#100+) and on the waiting list, is that if the check-in time goes beyond 8:00pm, (just saying there's a possibility with the large amount of sellers this year), they will be losing valuable time selling stuff.
I know the staff will do their best to make-sure everything goes smoothly, and while the Swap Meet won't be the same like it has been in previous years, we will have to make the best of the new location, times, etc.
