annual convention there as we speak. I say it's a coincidence because several years ago I used to work for a dental insurance company and I used to attend this convention when I worked for them.
Anyway I struck up a conversation with a couple of salespeople for a dental malpractice insurance agency who were from Northern California. I'm from the area and I asked if they were enjoying their visit. I asked them if the had a chance to go to DL or DCA and they said they would love to but they are just too busy. They couldn't even get the time to go to DTD. And they were staying at the Paradise Pier Hotel!
So in a nutshell I guess I'd have to agree with you there. It depends on the type of convention. If it is more of a business type convention people are less likely to go to DL. If it is an entertainment based convention like D23 or presumably a comiccon type event then people might be more likely to go.
On that note, this coming July for 5 days the convention center will be hosting FanFest as a part of the All Star Game being played at Angel Stadium this year. I'm thinking that this event, combined with the crowds for WOC, is going to really bring in the crowds at the DLR!
