I go to Shore Leave and Far Point on a regular basis, both of which have been held there for many years, although Far Point is at the....uh, is it a Crowne Plaza now?
Anyhow, to be honest, I do not think anything close to a Gen Con could happen in the Hunt Valley area. There's pretty good convention space in that Hunt Valley....uh, I almost called it a Mariott, I think it's a Wyndham now? Anyhow, the space in there is good, for a convention of about 2K. Can you imagine how insane that hallway would be from the Escalators over to Frank and Vinnies for a crowd the size of Gen Con? That space just can't handle a crowd much bigger than Shore Leave really.
And you've got the main hotel, and you could walk across the street from the Embassy, and that's it. There's other hotels there, but they are not walkable.
And the parking is not enough. I actually got so angry at an RV parked sideways in the parking lot last year, that I posted about it on Shore Leave's FB. There's not enough parking there.
I mean, I guess you could have it at the fairgounds, but that doesn't have any walkable hotels, with the possible exception of that Crowne Plaza that Farpoint is at. And that would be quite a walk.
I just don't think that's a viable location in teems of space and hotel rooms.
