SacCon is run by the same owners as SacAnime, and they do often use the Scottish Rites. However, that only really works for a 1 day convention, which is more like a dealers room/flea market than a traditional con with guests, panels, workshops, dances, game rooms, etc, etc, which work best in hotels, or con centers connected to hotels.
The other thing is, when we were downtown, especially in the Hyatt across from the capitol, we were able to make ourselves a real destination convention, albeit a small one. We drew in quite a few people from the Bay Area, and the central and Southern Valley who came out for the entire weekend.
Getting those people from other areas interested to come in (and then return for Kintoki-Con 2), is what allowed us to have Japanese guests flown in like Ryusuke Hamamoto and Koge-Donbo, and Moon Stream, as well as top tier American Voice Actors like Richard Epcar and Mary Elizabeth McGlynn, not to mention the slew of artists, musicians, fashion designers, writers, and more running panels and workshops.
So, while hotels like the Crowne Plaza Sacramento Northeast might be a possibility, it is also a total island (if you google where it is), and is not really central to other things, where our last two were central to Downtown and Old Sac with tons of after hours stuff. Also, Crowne Plaza has a maximum of 15,000 sqft of con space, where as the Hyatt has 27,000 in comparison.
I've thought about just trying to do a smaller one, but I am not sure fans would accept that after the first 2 were so much larger in space and scope.
I am interested to know what local fans think though.
